2 General Description
Principles of Operation
Luminescence is the emission of light energy resulting from "excited"
molecules returning to a resting state. When luminescence is initiated by
light, it is commonly referred to as fluorescence. When a fluorescent
chemical is exposed to light energy of an appropriate "color", electrons in
the molecules of the fluorescent chemical are "excited". A very short time
later, the electrons return to a resting state and in this process sometimes
emit a small amount of light energy. This energy is less than the excitation
energy and thus has a different color. That is, the emitted light
(fluorescence emission), is red-shifted from the excitation light and is much
less intense.
Fluorescent optodes (from optical electrodes) essentially measure the
intensity of light emitted from fluorescent dyes. The emitted light is
distinguished from excitation light by means of optical filters. Because
the excitation light energy is kept constant, the small amount of light that
results is changed only by the concentration of the analyte. The
concentration of the analyte is determined by the calculation of the
difference in fluorescence measured at a known calibration point and
fluorescence measured with the unknown concentration of analyte.
The P O 2 optode measurement principle is based upon luminescence, first
documented in the 1930's, and commercially utilized to measure blood
P O 2 in 1983. The relationship of luminescence to P O 2 is quantified by
the Stern-Volmer equation which describes how the fluorescence emission
intensity "I" is reduced as the PO 2 "P" is increased. Unlike conventional
electrochemical "Clark" P O 2 electrodes, the oxygen optode does not
consume oxygen molecules during the measurement.
The pH optode measurement principle is based upon pH-dependent
changes of the luminescence of a dye molecule immobilized in the optode.
Chemists have used such pH indicator dyes for many years to perform
acid-base titrations in turbid media. The relationship of luminescence to
pH is quantified by a variant of the Mass-Action Law of chemistry that
describes how the fluorescence emission intensity increases as the blood
pH is increased above the dye's characteristic pKa. pH optodes do not
need a reference electrode to measure pH; however, they exhibit a small
sensitivity to the ionic strength of the sample being measured.
The PC O 2 optode measurement principle is based upon placing a pH
optode behind an ion-impermeable membrane, just as conventional PC O 2
blood gas electrodes employ the Severinghaus C O 2 electrode construction.
As such, PC O 2 optodes suffer from non-selective interference from
volatile acids and bases in blood just as conventional PC O 2 electrodes.

2 General Description
During the measurement, light originating from lamps in the analyzer is
passed through optical filters so that specific colors are transmitted to
the sensors, causing them to emit fluorescence. The intensity of this
emitted light depends upon the partial pressure of oxygen (P O 2 ),
carbon dioxide (P O 2 ) or hydrogen ion concentration (pH) of the blood
in direct contact with the sensors, as described above. The light
emitted by the fluorescent sensors passes through lenses and additional
optical components. A filter is used to isolate specific colors of
interest from this returning light for measurement by a light detector.
The Na and K ion optodes are based upon the principle of Ion Selective
Electrodes (ISE’s). The optodes use ion selective recognition elements
(ionophores) similar to those used in ISE’s, however the ionophores are
linked to fluorescent dyes instead of electrodes. These types of dyes
have been used since the 1970’s to visualize and quantify cellular ion
levels in fluorescence microscopy and cell counters 8 . As the ion
concentration increases, these ionophores bind larger amounts of ions
and cause the fluorescence intensity to increase or decrease, depending
on the particular ion. Like the pH optode, the ion optodes do not need
a reference electrode, however they do exhibit a small pH sensitivity
that is automatically compensated in the AVL OPTI using the measured
pH.
The measurement of total Hemoglobin (ctHb) and oxygen saturation
(SO 2 ) uses the well-established principle of optical reflectance. Red
and infrared light a three wavelengths is directed at whole, nonhemolyzed blood within a precisely defined part of the cassette over the
O2 optode. The photons are partially absorbed and reflected by
erythrocytes in a manner proportional to hemoglobin level; at low
hemoglobin levels the unabsorbed photons strike the O2 optode’s pink
overcoat and are reflected back up through the blood a second time. A
portion of the reflected light exits the top of the cassette and is
measured by a detector in the instrument. The infrared wavelengths are
selected for the hemoglobin measurement because they are largely
independent of SO2, that is, the predominate forms of adult and fetal
hemoglobin absorb similarly within the 750 – 850 nm wavelength
range. The red wavelength is utilized for the SO2 measurement
because it is much more strongly absorbed by deoxyhemoglobin than
all other hemoglobins, and is picked close to the isobestic point for
oxy- and carboxyhemglobin. Maintaining high shear force just prior to
measurement minimizes sensitivity to erythrocyte aggregation (rouleau
formation).
The optical signal of the detectors is converted by the microprocessor
to a numerical readout in conventional units of measure and displayed
on the front of the device. Other values commonly used for the
assessment of oxygen and acid-base status are calculated from these
measured values.

2 General Description
The entire sample path of the OPTI cassette is filled with storage buffer
to keep the sensors stable during storage. In addition, the cassette
pouch is filled with a CO 2 atmosphere, which keeps the pH of the
storage buffer stable.
The cassette not only contains the sensors but also houses a distribution
valve (cassette valve), the sample fill port, an input/output port (I/O
port), a reservoir and a vent.
The function of the I/O port is to connect the cassette to the peristaltic
pump allowing sample aspiration and calibration gas to flow through
the cassette.
The storage buffer in the reservoir ensures stability over the shelf life
of the cassette.
The distribution valve has 2 functions: its hollow body serves as a
waste container, referred to as “waste”, holding storage buffer and
OPTI-trol. In addition, the cassette valve incorporates small channels,
called links that connect the sensor channel, the fill port, the vent and
the I/O port in different combinations. These different connections are
achieved by turning the cassette valve to different positions. Each
valve position has an assigned number. An unused cassette is set to
position 0, the home position. The diagram on page 2-9 shows the
valve positions and the connections for each position. E.g., position 2
connects the fill port via the valve link to the sensor channel and the
reservoir to the I/O port.
The OPTI 1 and OPTI CCA analyzers are microprocessor-based
instruments measuring optical fluorescence. The disposable, single-use
cassette contains all the elements needed for calibration, sample
measurement and waste containment. After reading the calibration
information specific to a cassette into the instrument by 'swiping' the
cassette package through a convenient bar code reader, the cassette is
placed in the measurement chamber. While the analyzer warms the
cassette to 37.0 ± 0.1 °C, the cassette valve is turned to position 5. In
this position, the I/O port is connected to the vent allowing the pump to
purge calibration gas. At the same time, readings are taken from all
sensors to ensure proper functioning. In addition, the fluid light gates
L1, L2 and L3 are calibrated.
Then the valve turns to position 1 which connects the I/O port to the
reservoir and the cassette sensors to the vent via the waste. The pump
starts pushing the storage buffer into the waste. L1 and L2 monitor the
movement of the buffer and the pump rate. After the buffer is pushed
into the waste, the valve turns to position 4, which connects the I/O
port to the reservoir and the sensors directly to the vent. The pump
2-7
2 General Description
first purges the cassette with calibration gas, then slows down during
the actual gas calibration passing the gravimetrically prepared gas mix
across the sensors. The pH sensor is calibrated via the precision
storage buffer. Calibration is completed when stable readings of all
sensors are obtained. The calibration process lasts from 15 to 80
seconds.
After calibration verification, the cassette valve turns to position 8
closing off all ports. The instrument now waits for aspiration of
sample fluid.
After pressing the J key, the valve turns to position 2, which
connects the fill port to the sensor channel and the reservoir to the I/O
port via waste. The pump starts aspirating the sample. During
aspiration, the sample light gates L1 and L2 check for sample type
(blood or clear fluid), bubbles and sufficient sample volume.
Once the sample has been aspirated successfully, the valve turns again
to position 4. After a short warm-up period, readings are taken from all
3 sensors. Once stable readings are obtained, the valve turns to
position 8 closing off all ports. The results are calculated and the
cassette is ready for disposal.
In case of an OPTI-trol measurement (OPTI 1 only), the user has the
option of terminating the measurement or introducing a subsequent
blood sample. If a blood sample is introduced, the OPTI-trol is purged
into the waste and the blood sample is aspirated and analyzed.

Plug J13 provides input from the Keypad and is fed to U49, an 8 bit serial input latch,
which decodes the selected keypad entries. The serial output is buffered and fed
directly to the microprocessor. U40A and U40B are dual D Flip-Flops, which provide
input to U51, one of eight decoders. U51 is fed to U49 to determine the correct
keypad row. U48A, B, C are part of a quad AND Gate package and provide debounce
circuitry for the keypad.
Serial data from the microprocessor is fed to the input of U50, a serial 8-bit shift
register to convert the serial display data to parallel data. The parallel data is
connected to the display through J13.
Main Board Circuit Diagram
Sheet 9
Serial data from the microprocessor is fed to U53, an 8-bit serial to parallel shift
register. This data provides the logic to control cassette detection LED’s and provides
output signals to the status LED. U44 is a seven-stage ripple counter used to divide the
32 kHz clock to a frequency of 1024 Hz. This divided clock and data from U53 are fed
to AND Gate U54A. This output provides the signal to drive the cassette light gates.
U52 is a parallel load to serial 8-bit shift register, which receives input from the
cassette light gates and other signals and provides serial data to the microprocessor.
Main Board Circuit Diagram
Sheet 10
Switch S1 is the main power switch and switches power to the OPTI 1 circuitry. Relay
K1 is used to switch input power either from the internal battery or main external
power supply. K2 is shown in the battery mode. When input power is supplied by the
external power supply, fuse F1 provides overcurrent protection for the input power.
U1 is a +5 Volt voltage regulator used to provide a regulated voltage supply to operate
U2. IC U2 is a battery charge controller with LED D46 indicating the battery charge
status. When D46 is solidly on, the battery is being charged and as the battery is fully
charged, D46 will blink rapidly to indicate the charge status. If D46 blinks slowly, it
indicates a defective battery or the battery temperature range has been exceeded.
A thermistor is included in the internal battery pack to provide temperature input to the
battery charge controller.

Switched power, either from the external power supply or internal battery is fed to this
circuit and is fused by F2 and F3. The +12 or +16 volts (battery/external power
supply) is fed to Q4, a Darlington Pair, which provides supply voltage used to heat the
sample measurement chamber (SMC). This input voltage is also fed to U12 a
switching 5-Volt regulator, which supplies +5 volt power to the digital circuitry (ssv)
and printer (pvcc).
U14 is a +12V voltage regulator and feeds U20, a positive to negative voltage
converter. The negative voltage output from U20 is fed to U25 to provide a regulated 5 volt output. An additional +5V voltage regulator U21 is also used.
Main Board Circuit Diagram
Sheet 12
The SMC temperature circuitry comprises two temperature control circuits that control
the top plate heater and the optics module heater (lower plate). U26, a +5 volt
regulator, provides a reference voltage used by both circuits. Operational amplifier
U33D along with potentiometer R97 and R95 provide adjustment and control for both
heater circuits. IC U32A and U32B provide the optic module heater control while
U32C and U32D control the top plate heater.
Main Board Circuit Diagram
Sheet 13
This circuitry with inputs from sheet 11 controls the heater transistors in the SMC
assembly. U34D and U43C are connected to the base and emitter of the optics module
heater transistors. The signal OPTICCTRL (from sheet 11) causes the optics module
heater transistors to conduct more when the temperature of the optics module needs to
be increased to maintain regulation. IC U43A operates similarly as U34D and is
connected to the top plate heater transistor.

This circuit converts resistance provided by the NTC’s to a voltage for the temperature
control of the top and bottom plate heaters located in the SMC. Op Amp U33A is fed
an input from the NTC located in the optics module heater (bottom plate), an output
voltage representative of the input NTC resistance. U33C is an identical circuit and
receives the NTC input from the top plate NTC. U33B is fed the reference voltage
input and provides the battery backup reference voltage (signal BCHRG2) which is fed
to the battery charge controller located on sheet 1.
Main Board Circuit Diagram
Sheet 15
The two digital to analog converters (DAC’s) U17 and U23 control the sample sensor
brightness or intensity for the sample sensor LED’s, LG1 and LG2 located in the SMC
assembly. A comparison is made with the values stored in memory and provides a
self-calibration. This signal is fed to each sample sensor anode, which controls the
intensity of the sample sensor LED’s. The reference voltage signal is fed to IC U22B,
which changes the impedance for the barometer circuit located on sheet 16.
Main Board Circuit Diagram
Sheet 16
The analog to digital converter U15 receives a parallel input of 8 analog signals and
converts these voltages to a serial digital signal which is fed directly to the
microprocessor via signal HIS0. The parallel input signals, which are labeled on the
schematic, can be observed on the analyzer display when the diagnostic menu is
selected.

The internal barometer circuitry is comprised of the pressure transducer (BARO1) and
the associated circuitry. The output voltage of BARO1 changes according to the
changing atmospheric pressure. Op Amps U16 A, B, and C are used to calibrate the
output pressure and correlate this pressure to barometric pressure standard. The output
voltage at TP 15 represents barometric pressure in mmHg according to the following
formula:
Voltage + 3000 = BP mmHg

The valves and stepper motors used in the OPTI 1 analyzer are controlled by the
circuitry contained on this schematic sheet. U47, a serial to parallel latch, receives
input from the microprocessor and provides the control signal for the gas valve along
with other signals as labeled. U28 is a serial to parallel decoder which decodes the
direction and enable signal for the valve drive, peristaltic pump and the printer. U36 is
the driver for the valve drive motor and is fed signals directly from the microprocessor
(TP0 - TP3) and an enable signal from U28 to provide four motor drive signals to
valve drive stepper motor. The peristaltic pump is controlled by U27, a stepper motor
controller, which feeds U35, the driver for the peristaltic pump stepper motor.
Main Board Circuit Diagram
Sheet 19
The internal printer is controlled by this circuitry. U45, a serial to parallel printer
driver, receives an enable signal and converts serial data from the microprocessor to a
parallel output which is fed to the printer print heads. The printer motor is controlled
and driven by U31 and U42. U31, the printer controller receives an enable and
direction signal which feeds U42, the motor driver for the printer stepper motor.

6 Test Programs and Diagnostics
OPTI 1 System
The AVL OPTI 1 is equipped with diagnostic routines designed to assist the user in
testing the operation of the each system component. These tests can be selected in the
Diagnostics Menu. An overview of the diagnostic tests available is located in Section
2. This section describes each diagnostic test and the expected result.
Diagnostic 1
Barometer
The BARO test displays the system barometric pressure in a real-time mode. This test
can be used to verify the internal pressure transducer is measuring correctly. The
barometric pressure should be compared to the laboratory reference standard and
calibrated accordingly. The operator can adjust the barometric pressure by entering
the correct value in the SETUP - BARO menu. To calibrate the internal barometer
follow the adjustment procedure outlined in Chapter 7.
Battery
The OPTI 1 may be powered by an internal battery pack or by an external battery
charger, which is supplied with the analyzer. This test allows the user to determine the
voltage of either the battery or external battery charger. When the charger is plugged
in and connected to the analyzer, the display indicates the battery charger voltage.
When the analyzer is powered from the internal battery, the displayed voltage is the
battery voltage. When the internal battery powers the OPTI 1, the voltage must be
greater than 11.2 volts for correct operation. While the external battery charger is
connected, the internal battery is being charged. The main board contains the required
circuitry to monitor and control the battery charging system. An LED is visible
through the rear cover indicating battery charge status. A solid ON light indicates the
battery is charging, while a fast flashing light (4 times per second) indicates the battery
is fully charged. The battery LED will be OFF when the analyzer is not connected to
the external charger. A slowly blinking light (once per second) indicates a very cold,
very hot or defective battery.
6-1
6 Test Programs and Diagnostics
Temperature
The temperature diagnostic test displays three system-operating temperatures. T1
displays the SMC top plate temperature, T2 displays the SMC lower plate temperature
and T3 displays the ambient temperature of the internal chassis and is used for the fan
control. Circuitry on the main board, optics module, and SMC heater board provides
temperature control for the analyzer. The following specifications are required for
proper operation:
T1 = 37.00° C ±0.05° C
T2 = 37.15° C ±0.05° C
T3 = Internal analyzer temperature
Adjustment of the temperature circuitry is described in Chapter 7, Adjustments.
Gas Pressure
The newly installed calibration gas cylinder contains a gas pressure of 140-psi (9.7
bar) and is regulated and monitored by the gas module assembly. The gas pressure
sensor portion of the module provides gas pressure status to the OPTI 1 analyzer. If
the gas bottle pressure falls below approx. 35 psi, the switch closes (low pressure).
The pressure needs to be above approx. 50 psi for the switch to open (high pressure).
This diagnostic test indicates HIGH PRESSURE or LOW PRESSURE depending on
the remaining gas cylinder pressure. When this diagnostic test is completed, an
additional screen is displayed to allow replacement of the gas bottle and a gas purge
sequence to be initiated by the user.
Cleaning
The OPTI 1 provides an automated cleaning routine that can be performed by selecting
the diagnostic cleaning menu. Operator instructions are displayed to provide the user
with a step-by-step guide for completion of the cleaning routine. First, the operator
will be instructed to remove the peristaltic pump cartridge followed by pressing J.
Next the operator will be instructed to place a syringe in the front peristaltic pump
receptacle. The syringe should contain a mild cleaning solution such as a 30% bleach
solution. Press J upon completion. The OPTI 1 will now instruct the operator to
perform a wash. To do this, move the cleaning solution back and forth to flush the
fluidic tubing. A tissue should also be placed at the inlet port of the SMC to catch any
cleaning solution, which may be pushed, through the port. Press J upon completion.
The operator will now be instructed to reinsert the pump cartridge. Press J to
confirm this action and complete the cleaning procedure.
6-2
6 Test Programs and Diagnostics
Flow
Performing a flow test requires the use of a new cassette. The purpose of the flow test
is to check proper operation of the pump, gas module and to detect leaks downstream
from the pump.
At the end of the flow test, a pass/fail as well as two flow numbers are displayed. If
the flow numbers are 99.99, this part of the test failed and no number could be
obtained.
Press J to start the test. First, the gas pressure is turned on (tubing upstream from
pump is pressurized). With the pump stopped, the fluid light gates L1 and L2 check
for the buffer to remain in the cassette. If the buffer is pushed out, the test fails and the
pump cartridge needs to be replaced.
Now the pump starts pumping slowly, while L2 is looking for the trailing edge of the
buffer. If the trailing edge is not detected within a certain time-out, the test fails.
Check for leaks downstream from the pump. Replace the SMC gas seal and the pump
cartridge receptacles.
Once L2 has detected the trailing edge, L1 is looking for the trailing edge of the buffer.
L1 must detect the trailing edge between 1.2 seconds and 5.2 seconds. The actual time
is indicated by the first number on the display at the end of the test. If the number is
less than 1.2 seconds, replace the gas bottle and check the output pressure of the gas
module (2.5 psi ± 0.5 psi).
Next, the system reverses the pump direction and measures the time of the buffer
movement between LG1 and LG2. Since now the pump transports the buffer against
the gas pressure, the time needs to be between 4.0 seconds and 8.0 seconds to pass the
test. The second number displayed at the end of the flow test is the actual time. If the
time is below 4.0 seconds, replace the gas bottle and check the output pressure of the
gas module. If the time exceeds 8.0 seconds, replace the pump cartridge.
Optics Test
During the optics test, the optics module is warmed for 30 seconds to stabilize the
optics system. Readings are then taken for each of the three channels for one minute.
The test results are then calculated and printed to include the mean value of each
channel’s intensity, noise and CV %.
To test the proper function of the optics module and electronics, start the Optics test
and insert an SRC (Low, Medium or High level).
The values printed at the end of the test should be within the following limits:
pH:
PCO2:
PO2:
AVG 40’000 to 160’000
AVG 40’000 to 160’000
AVG 25’000 to 160’000
%DR: -1.0% to +1.0%
%DR: -1.0% to +1.0%
%DR: -1.0% to +1.0%
%SEE: 0.0% to 0.1%
%SEE: 0.0% to 0.1%
%SEE: 0.0% to 0.1%
If a value is out of range, repeat the test with another SRC.

Keypad Test
The keypad test when selected responds with the pressed key’s information displayed
in the analyzer’s LCD display. Each key can be pressed successively until all keys
have been tested. To exit this diagnostic routine, press E twice to return to the
diagnostic menu.
Display Test
The display test can be selected to test the LCD display module. As this test is
selected, each of the 24 characters in both rows of the display will be illuminated to
indicate the function of the entire display module. The test will repeat every several
seconds until E is pressed to end the test.
Barcode Test
The barcode test is designed to test the function of either the internal barcode or the
optional external barcode. To perform the barcode test press J to start the test.
Swipe a valid barcode label and the analyzer will display the barcode information on
the LCD display.
RS232 Test
The RS232 Serial Interface test is included to test the serial interface function. To
perform the test, first select the RS232 test. Displayed instructions will request the
user to jumper pin 2 & 3 of the 9-pin serial interface connector on the rear panel of the
analyzer. When the jumper is in place press J to start the test. Test results will be
displayed indicating either PASS or FAIL.
6-4
6 Test Programs and Diagnostics
Cover Test
The cover test is used to test the function of the SMC cover. When the cover is closed
the display will indicate Closed. Open the SMC Cover and the display should indicate
Open. To exit this test, press the E key and return to the diagnostic menu.
Fset
The Fset menu permits viewing and modification of factory-set values stored in the
EEPROM. At the prompt Password <ENTER> type 3350 <ENTER>.
IDAC1 and IDAC2 are default DAC values for LG1 and LG2. The default DAC
values are used only if no valid DAC values are available from the last measurement.
The serial number displayed should match the last four digits of the serial number
printed on the serial number label.
pH, CO2 and O2 false light values are subtracted from the signal intensities and
compensate for amplifier offset and photodiode dark currents.
CDetect Low Limit is used as the reference value for the cassette detect sensor with
SMC cover open and no cassette inserted.
CDetect Up Limit is used as the reference value for the cassette detect sensor with
SMC cover closed and cassette inserted.
CDetect Low Offset is added to the CDetect Low Limit and is the threshold for a
‘cassette present’ condition. The CDetect Low Offset is always 100.
CDectect Up Factor is multiplied with the CDetect Up Limit and is the threshold for
a ‘cassette not present’ condition. The CDectect Up Factor is always 0.6.
The Home Offset value indicates the number of motor steps between the home light
gate position and the cassette valve home position.
Gas Module Type: GR RE allows selection between ‘green dot’ and ‘red dot’ gas
modules. Depending on its revision level, the gas module MB7001 has either a green
or red dot applied. Generally, instruments with S/N < 1530 are marked with a red dot.
PHR Correction: 160. These are factory-set optics calibration values which should
not be changed.
PCR Correction: 75. These are factory-set optics calibration values which should not
be changed.

Diagnostic 3
Valve Test
The gas module incorporates two gas valves: an On/Off valve on the high-pressure
side which enables/disables the gas flow, and a 3-way valve, which connects the pump
to the vent or to the gas module. Both valves are wired in parallel, i.e. they are
activated/deactivated simultaneously.
The valve test allows the user to test the gas valves. When the test is started, the
analyzer displays the valve status. Pressing the right or left arrow key will turn OFF
and ON the valve. Press E to exit the valve test.
This test can be used for checking adequate gas flow and the output pressure of the gas
module (2.5 psi ± 0.5 psi). Remove the pump cartridge and turn the valve on. The gas
will free-flow out the rear pump cartridge receptacle. Connect a piece of tubing and
submerge it in water to check for adequate flow. Vigorous bubbles indicate adequate
flow. If flow is inadequate, replace the gas module. To check the output pressure,
connect a calibrated, digital pressure meter to the rear pump receptacle. If the pressure
is outside the specified limits, replace the gas module. Note that output pressure is
factory-set and cannot be adjusted.
Vdrive Test
The valve drive test is used to test and determine the position and movement of the
valve drive. Select the Vdrive menu to begin the test. Position 0 will be displayed.
Press the right arrow key to select valve position 1 - 12 and press J. The valve drive
will move to the desired position. To test the home position, select position 0 and
press J. When the valve drive has reached home position, insert a new cassette.
The cassette should fit over the valve drive pins without any resistance. The home
position can be adjusted using the Fset menu. Increasing the number will adjust the
home position counter-clockwise, decreasing the number will adjust it clockwise.
Peristaltic Pump Test
The pump test is used to test the function of the peristaltic pump. When the pump test
is selected, the OPTI 1 will perform an automatic test of the peristaltic pump including
clockwise and counter-clockwise rotation and a cycling of each pump speed used in
normal operation. Once the test routine is started, correct pump operation can be
observed by opening the printer access cover.
Note that the pump speed is computer-controlled and adjustment is therefore not
necessary.

memory. The analyzer displays MEMORY OK when the system successfully verifies
the memory.
Software Version
Selecting the Software Version menu displays the currently installed software
revision level. Pressing the right arrow key displays the software version for the optics
module.
Reports
With the Reports menu, the user can select one of four reports to be printed. The
Error Report saves the last 50 system errors and can be printed. When the number of
system errors exceeds 50 the oldest error is deleted and replaced by the most recent
error. A Calibration Report can also be printed which provides a calibration data
summary of the stored patient and QC measurements. The third report is an SRC
Report, which provides a summary of all stored SRC results. The Configuration
Report prints out all user selectable settings. A printout of this report is particularly
helpful prior to erasing memory (e.g. software update).

Valve Test
The gas module incorporates two gas valves: an On/Off valve on the high-pressure side
which enables/disables the gas flow, and a 3-way valve that connects the pump to the
vent or to the gas module. Both valves are wired in parallel and they are activated/
deactivated simultaneously.
The valve test allows the user to test the gas valves. When the test is started, the
analyzer displays the valve status. Pressing the right or left arrow key will turn OFF
and ON the valve. Press E to exit the valve test.
This test can be used for checking adequate gas flow and the output pressure of the gas
module (2.5 psi ± 0.5 psi). Remove the pump cartridge and turn the valve on. The gas
will free-flow out the rear pump cartridge receptacle. Connect a piece of tubing and
submerge it in water to check for adequate flow. Vigorous bubbles indicate adequate
flow. If flow is inadequate, replace the gas module. To check the output pressure,
connect a calibrated, digital pressure meter to the rear pump receptacle. If the pressure
is outside the specified limits, replace the gas module. Note that output pressure is
factory-set and cannot be adjusted.
Flow Test
Performing a flow test requires the use of a new cassette. The purpose of the flow test
is to check proper operation of the pump, gas module and to detect leaks downstream
from the pump.
At the end of the flow test, a pass/fail as well as two flow numbers are displayed. If
the flow numbers are 99.99, this part of the test failed and no number could be
obtained.
Press J to start the test. First, the gas pressure is turned on (tubing upstream from
pump is pressurized). With the pump stopped, the fluid light gates L1 and L2 check
for the buffer to remain in the cassette. If the buffer is pushed out, the test fails and the
pump cartridge needs to be replaced.
Now the pump starts pumping slowly, while L2 is looking for the trailing edge of the
buffer. If the trailing edge is not detected within a certain time-out, the test fails.
Check for leaks downstream from the pump. Replace the SMC gas seal and the pump
cartridge receptacles.
Once L2 has detected the trailing edge, L1 is looking for the trailing edge of the buffer.
L1 must detect the trailing edge between 1.2 seconds and 5.2 seconds. The actual time
is indicated by the first number on the display at the end of the test. If the number is
less than 1.2 seconds, replace the gas bottle and check the output pressure of the gas
module (2.5 psi ± 0.5 psi).
6-18
6 Test Programs and Diagnostics
Next, the system reverses the pump direction and measures the time of the buffer
movement between LG1 and LG2. Since now the pump transports the buffer against
the gas pressure, the time needs to be between 4.0 seconds and 8.0 seconds to pass the
test. The second number displayed at the end of the flow test is the actual time. If the
time is below 4.0 seconds, replace the gas bottle and check the output pressure of the
gas module. If the time exceeds 8.0 seconds, replace the pump cartridge.
Display Test
The display test can be selected to test the LCD display module. As this test is
selected, each of the 24 characters in both rows of the display will be illuminated to
indicate the function of the entire display module. The test will repeat every several
seconds until E is pressed to end the test.
VDrive Test
The valve drive test is used to test and determine the position and movement of the
valve drive. Select the VDrive menu to begin the test. Position 0 will be displayed.
Press the right arrow key to select valve position 1 - 12 and press J. The valve drive
will move to the desired position. To test the home position, select position 0 and
press J. When the valve drive has reached home position, insert a new cassette.
The cassette should fit over the valve drive pins without any resistance. The home
position can be adjusted using the Fset menu. Increasing the number will adjust the
home position counter-clockwise, decreasing the number will adjust it clockwise.
Peristaltic Pump Test
The pump test is used to test the function of the peristaltic pump. When the pump test
is selected, the OPTI CCA will perform an automatic test of the peristaltic pump
including clockwise and counter-clockwise rotation and a cycling of each pump speed
used in normal operation. Once the test routine is started, correct pump operation can
be observed by opening the printer access cover.
Note that the pump speed is computer-controlled and adjustment is therefore not
necessary.
Keypad Test
The keypad test when selected responds with the pressed key’s information displayed
in the analyzer’s LCD display. Each key can be pressed successively until all keys
have been tested. To exit this diagnostic routine, press E twice to return to the
diagnostic menu.

database. Cumulative statistics printed or displayed in the
system software are calculated based on the stored data. A
minimum of 2 data points is required in order to calculate
statistical results. This message is displayed when too few
records exist in the database to provide a result. Enter
additional QC or SRC measurement data when this message
is displayed.
When a new lot of QC material is to be run, the assay or
package insert values must first be entered (under password
control). As the operator enters a new lot number, the OPTI
will prompt the operator to print and then delete the old QC
data. As the QC records are deleted, this message is
displayed to confirm the deletion of the QC database has
occurred.
If the sample measurement chamber (SMC) cover is opened
during a critical time (during calibration, aspiration or
measurements), this message will be displayed. Close the
SMC cover to continue normal operation.
New SRC Lot !
During an SRC measurement, the SRC ID number is checked by
the barcode information. If the OPTI analyzer detects an ID
number that differs from that of previous SRC measurements, the
New SRC warning is displayed. The operator may select J to
continue or E to exit the SRC measurement process.
Cassette Expired
If an operator swipes a cassette barcode and the expiration date of
the cassette has been exceeded, this message will be displayed.
Check the analyzer TIME and DATE for the correct entry. If the
time and date are correct replace the cassette lot with an in date lot.

Troubleshooting
The AVL OPTI provides display messages indicating the status of the analyzer. The
previous section describes the conditions in which error, warning or system
information messages may occur. This section contains troubleshooting tables to
define possible causes and instructions for remedial action. In addition,
troubleshooting flowcharts are provided for the most common error occurrences.
Error Message
WARNING -Low Battery
1 Test Remaining <ESC>
Possible Causes
Battery voltage >11.2 and
< 11.8 volts.
Remedial Action
Replace battery pack with a
fully charged battery.
Plug in battery charger, check
Charge LED is ON. The
charger will charge a depleted
battery while connected to AC
power in approximately 6
hours.
If the battery will no longer
accept a charge replace the
battery with a new battery pack.
Check the charge LED status;
a solid ON indicates the battery
is charging, a fast flashing ON
LED (4 times/second) indicates
battery is fully charged.
If the charge LED is OFF this
indicates the charger is not
connected. Replace charger or
replace the main board.
A slow flash (1 flash per
second) indicates the battery
voltage is below 9.5 volts or the
battery thermistor senses an
excessively hot or cold battery.
Replace the battery if this
indication persists.
