2 Product Description
2.0 Product Description
2.1
Mechanical Assemblies
The analyzer is designed to
calibrate using calibration standards and reference solution
contained in a reagent pack.
The tubing automatically connects with the pHOx when the
pack is placed into the analyzer. Likewise, a space is provided for a plug-in control
pack. The content and serial number of the pack is
coded in a “Dallas Semiconductor Add-Only Memory,”
which is read by a One-Wire
MicroLAN® system. The analyzer has 4 major mechanical
assemblies to move calibrator
or sample in front of the biosensors.
Figure 2-1 Flow Diagram
2-1
2. Descrip.
The pHOx analyzer accepts syringe or capillary samples through a sample probe.
The operator selects the sample mode via the keypad. The probe moves from its
home position in the analyzer to an extended 45° position for syringe sampling. If
the capillary sample is selected, the probe moves to a horizontal position that is
back inside the capillary adapter.
pHOx Service Manual
2.1.1 Pump
The analyzer uses one pump (PN 21492) for 2 functions. The pump aspirates
either sample or calibration standards from the sample probe, through the sensor
module/reference electrode, through a solenoid actuated pinch valve, and delivers
to the waste bottle of the reagent pack.
The second function of the pump is to aspirate the reference solution from the
reagent pack and deliver it to the reference electrode through a solenoid actuated
pinch valve.
2.1.2 Sampler Assembly
The sampler assembly (PN 21504) utilizes a probe that rotates to 1 of 3 possible
positions. The HOME position is vertical with the tip of the probe seated against a
"Fluid Fountain” assembly that is the common port of the rotary valve.
The syringe position is the probe tip extended out in front of the analyzer at approximately a 45° angle. The capillary position is horizontal, but the tip is totally
inside the capillary adapter. This allows the capillary to be used without a separate
adapter. (This position is also used to change the capillary adapter.)
The capillary adapter is pushed onto the end of the sampler. Extending the probe
outward from the capillary position ensures that the probe will be seated inside
of the adapter. The sampler will exert enough force to push the adapter off of the
sampler if it is not aligned correctly.
2.1.3 Rotary Valve Assembly
The rotary valve assembly (PN 22215) has one common port connected to the
sampler’s ﬂuid fountain. Each calibration standard and quality control standard
is connected to a port on the rotary valve. The rotor positions a central port connecting one of the ﬂuids to the outlet port. The outlet port is connected to the Fluid
Fountain by the S-Line. Starting the pump aspirates the selected ﬂuid into the ﬂow
path.
The rotary valve's manifold also has positions that allow air to enter the S-line. Refer to the replacement procedures for actual positions.

2 Product Description
2.1.4 Sensor Module Assembly
2.2
Electronic Assemblies.
2.2.1 Power Entry Module
The power entry module (PN 22818) provides the interconnect to wall power. The
fuses are found in the accessory kit for the operating voltage (120 VAC PN 22814,
236 VAC PN 22817). The power entry module connects to the power supply
through TB1.
2.2.2 Power Supply
The power supply (PN 21602) provides all of the power requirements for the analyzer. The analog and logic voltage used in the pHOx are + 5VDC. The stepper
motors are driven by +24 VDC. This module has no repairable parts inside. The
power supply connects to the digital control board by TB2.
2-3
2. Descrip.
The Sensor Module Assembly contains the measuring sensors, ﬂow cell, and
preheater. The measuring sensors clip into place upon insertion. The sensors have
contacts instead of cabled connectors. When mounted, the sensor module forces
the sensor contacts to align with the matching contacts on the left/right interconnect boards. The module also contains the light sources and detector for the
SO2% channel and 2 air detectors.
Please refer to the drawing section and Appendix A for individual part numbers.
pHOx Service Manual
2.2.3 Digital Control Board
There are 2 Digital Control Boards: all units with monochromatic display use
PN 24292, and all units with a color display use PN 40797. The main controlling
board of the analyzer uses an Intel 386X processor with the following integrated
peripheral functions:
•
Clock and Power Management unit
•
Watchdog Timer Circuit
•
Asynchronous Serial I/O unit
•
Synchronous Serial I/O unit
•
Parallel I/O unit
•
Refresh control unit
•
JTAG- Complaint Test Logic Unit
The digital control board provides one 72 pin socket for a 4 MB SIMM module of
RAM. This volatile memory stores the calibration, slope, and millivolt data.
Major circuit identiﬁcation:
U25 is the main clock generator; it is crystal controlled 14.318 MHz and a phaselocked-loop frequency generator. This generates a 50.11 MHz CPU clock,
14.318 MHz for VGA video timing, and 1.84 MHz for Baud rate generation.
U35 is the real time clock containing a battery which will retain the date/time,
setup options, daily QC (up to 144 points), Error log (last 96 errors FIFO),
and sample counter data. The battery has an expected 10 year life.
U37 PEROM stores the monthly (256 data points) and YTD QC data, QC setup
information, and recognition of the QC ﬂuid pack presence.
PCMCIA contains the operational program and boot program. This card must be
in place for the unit to function.
U43 is the video control chip. U26 controls the printer output and the I/O ports
Comm 1 and Comm 2. U36 is the DUART that controls the Comm 3 I/O
port.
U16 provides the serial interface for the (RMS) interface and ﬂuid pack memories.
The mechanical devices are controlled by U18. The Keypad and “home” sensors
for the rotary valve and sampler are ported through U18. The stepper motors are 4
phase stepper motors. U18 controls the speed and direction each phase is powered. U3 and U4 provide the power for each winding of the pump motor. U5 and U6
power each phase winding of the sampler motor. U7 and U8 power each phase of
the rotary valve motor.
U18 also provides the logic signal to operate the other mechanical devices. Typically, the devices are connected to either 12 VDC or 24 VDC and the logic provides
a ground path through a transistor. The waste valve solenoid (12 VDC) grounds
through Q3, the reference solenoid (12 VDC) through Q4, the sensor module lamp
(24 VDC) through Q6, and the preheater (24 VDC) through Q2. The 24 VDC valve
boost circuit is on the board but not used on the pHOx analyzer.

Individual circuits are protected from an over current condition by the use of Positive Temperature Coefﬁcient Resistors (PTC). These resistors act as a direct short
if the current is below a set current. If the current increases, the resistors heat up
and open, similar to a fuse. When the device cools off, the connection is remade,
allowing the circuit to function. The following lists these devices:
R22 - Solenoid common boost circuit (not used on pHOx)
R24 - Heater power circuit
R29 - Printer motor power
R43 - Print Head heater power
R44 - +24 VDC
R45 - +5 VDC
R71 - Bar Code Reader (+5 VDC out)
R249 - Distribution board power (This board is mounted in the door.)
The LED indicators on this board are mostly unused. All will light at power up and
then go off. The exception is D8 - 100 Hz Clock. D9 - 386 Strobe will appear to be
always on. D7 is your program fail indicator and will come on with a software reset.

•
Right Sensor Interface board J7 - PO2, Na+
•
Sensor module J4 -SO2% detector, Preheater temp, ADT2, ADT3/Hct
•
Mechanical assemblies J3 - ADT1
Barometric pressure sensor U9 is on the analog board. The Analog to Digital Conversion (ADC) is performed by U31. The signals are multiplexed through U26 and U32.
Preheater temperature control circuits are on the analog board. +24 VDC are
ported through J3 to the SO2%/sensor module board (J4). The heater power wiring is protected on the digital control board by a PTC Resistor; the Heater has an
in line thermostat (50°C) in the sensor module. The thermistor has 18.25 Kohms
resistance at 37°C. The signal will change at a rate of 22.5 millivolts/0.1°C.
There are 4 ADTs in the system. ADT1 holds the sample probe (40 uL setting).
ADT2 at the inlet to the sensor module (70 uL). ADT3 is at the input to the sensors
and is also used for the Hct. ADT4 is in the reference electrode housing.
Logic and analog power is supplied to the analog board from the digital control
board. Logic voltage (+5 VDC) enters J1 pin 14. The analog +5 VDC enter J1 pin 3
and -5 VDC J1 pin 4. The analog board provides power to the SO2 board through
+5 VDC J4 pin 5 and -5 VDC J4 pin 6.
2.2.5 SO2 Control Board
SO2 Control Board is an integral part of the Sensor module. It controls the 2 LED
light sources that glow at 880 nM and 660 nM, respectively.

2 Product Description
2.2.6 Electrode Interface Boards
The electrode interface boards are found only on pHOx
and pHOx Basic.
The Electrode Interface Boards have 2 part numbers: PN 20641 (Left) and
PN 20674 (Right). The electrodes are wireless. The electrodes have point contacts
which engage the Interface board contacts when inserted into the sensor module.
The left interface board, connecting to the analog board through J6, has 3 sets of
contacts: one set for the reference electrode/ADT4, one set for Na+, and one set
for PCO2 sensors. The reference electrode/ADT4 has 3 individual point contacts
while the Na+ and PCO2 have 2 individual point contacts.
The right interface board has 2 sets of contacts: one for the pH and one for the
PO2 sensors; each consisting of 2 individual point contacts. This board is connected through J7 to the analog board.
2.2.7 Door Assembly Electronics
The door assembly electronics include the Display Assembly, the Distribution
Board, and the Keypad Assembly. The digital control board sends/receives signals
to the door via the ﬂat cable J104 on the distribution board.
NOTE:
See Section 3.13 for part numbers that are model speciﬁc.
The keypad, which is glued onto the door, connects to the distribution board via
J102 and has a ground cable clamped to the conductive surface on the inside of
the door. The Analyze key also connects to the distribution board through this connector.
The distribution board also provides the signal path to the display assembly and
power to the display back lighting lamp. The display is a liquid crystal, graphics display. It has a 320 x 240 dot matrix (1/4 VGA) yielding a 122 x 92 mm (4.99 x 1.33
inch) viewing area. This translates to a 40 x 20 character display using a standard
character set. The display is backlit by cold cathode ﬂuorescent tube (CCFT).
An 8 ohm voice coil loudspeaker is mounted on the distribution board, producing
all associated sounds.

4.0 Troubleshooting Information
This section contains suggestions for individual error codes, cycle information to
help identify the cause of an error condition, and hints on basic troubleshooting.
1.
Troubleshooting is recognizing the variance from normal operation. The
calibration cycle can be used as the sequence of events where the cycle
response and results are known.

Calibrator Functions other than calibration.
PO2 Std. B is used to ﬂush the system.
PO2 is monitored on all ﬂuids in the Calibrator pack. If the PO2 millivolt reading varies from that of room air, a 72 Delta mV error is generated indicating
a contaminated calibrator pack.
Std. D has surfactant and is used to clean the ﬂowpath between pump cycles.

4. Trouble.
Pressing the soft key under the Service Flow Test brings up a screen that displays
the results of this test. On this screen, pressing the soft key under Run Test causes
the unit to pump each ﬂuid twice: once with the Reference valve shut and once
with the Reference valve Open.
The expectation is that the ﬂow time will increase with the decrease in vacuum
caused by pumping reference solution into the waste line junction in the reference
electrode. Ideally the 2 pump windings are equal and the ﬂow time will double with
the reference solenoid valve open.
The pumping times will yield 2 pieces of information:
1. The individual ﬂow times appear at the end of pumping that ﬂuid.
2. All the ﬂuids will pump at the same rate. Usually Standard D is the one standard that varies in ﬂow rate from the other ﬂuids.
A good rule of thumb for the ﬂow rates is
pHOx Basic/BiopHOx and pHOx is in the 1000 – 1200 range.
pHOx Plus/C is in the 1200 – 1300 range.
pHOx Plus L pumps in the 1300 – 1400 range.
pHOx Service Manual
At the end of the Test, the Average ﬂow time for Reference Valve Closed and
Reference Valve Open is displayed. A ratio of the average times is presented. The
ratio should fall between 0.5 – 0.65.
•
Ratios approaching 1 indicate the loss of reference ﬂow.
•
Ratios approaching 0.0 indicate an obstruction or air leak in the system
before the ﬂowpath reaches the Reference electrode.

Flow Problems
NOTE:
Each of the following troubleshooting procedures has an
associated ﬂow diagram that may be found at the end of
this chapter.
General procedures when isolating ﬂow problems:
NOTE:
Refer to the FLOW TEST decision tree. Do not be confused with the Flow Test Cycle that only shows the ﬂow
times.
Unit calibrates, but the sample will not aspirate. This usually means you have an air
leak into the system. The sample, being more viscous than the aqueous standards,
causes more vacuum to be created by the roller pump. If a membrane is leaking,
this increase in vacuum will pull the aqueous ﬁll solution from the electrode, easier
than pulling sample from the probe. Likewise, a poor connection at the interconnect tubing or between the electrode sealing washer and the sensor module will
allow air to enter easier than pulling sample up the ﬂow path.
•
Check the connections between probe and sensor module, sensor module,
and reference electrode.
•
Check the electrodes for the loss of internal ﬁll solution.
•
Check the ﬂow cell window during a pump cycle, looking for bubbles entering
the ﬂow path or pump and waste tubing.
A No ﬂow or obstructed ﬂow cause can be isolated by performing the FLOW TEST.
The ﬂuidic system can be isolated into three large sections. This will limit the area
of your search. The 3 sections are Fluid Pack to Fluid Fountain, Sampler/Sensor
module, and W/R to Waste tubing. Use the SYSTEM TEST screens to control the
mechanical devices.
1.
2.
3.
4.
5.
NOTE:
4-10
Extend the sampler to the syringe position.
Open the waste line solenoid.
Turn on the pump and attempt to aspirate water then air from a sample
cup.
If water is aspirated from the cup, the sample probe, sensor module, external
tubing, and waste line are functioning. The problem exists between the Fluid
Fountain and Fluid Pack.
If water is NOT aspirated from the cup, remove the tubing from the outlet
port of the Reference electrode. Place it in a cup of water.
This assumes the waste solenoid has functioned and is
not pinching the tubing.
4 Troubleshooting
6.
7.
If step 5 fails to aspirate from the cup, the problem lies between the W/R
tubing and the waste bottle of the Fluid Pack.
If Step 5 does aspirate water, the problem is in the Sampler/ Sensor module.
4.2.1 Isolating a Plug in the W/R to Waste Tubing
NOTE:
1.
3.
4.
5.
Disconnect the waste tubing from the reference electrode and place in a cup
of water. If water is NOT aspirated, there is a plug.
Lift the waste tubing out of the waste solenoid. If ﬂow starts, the valve is dirty.
Clean the dirt from the waste solenoid or replace it.
If ﬂow does NOT start, remove the waste line from the front panel connection. If water ﬂows from this tube there is a plug in the internal waste tubing
or waste bag of the ﬂuid pack.
Turn off the pump. Connect a syringe of water to the waste port on the front
panel. Attempt to inject water through the line to clear the plug.
If there is no ﬂow, remove the Fluid Pack to ensure the problem is not a
poorly seated or damaged waste connection. Should the problem continue,
replace the internal tubing set.
4.2.2 Isolating a ﬂow problem in the Sampler/Sensor module
1.
2.
3.
4.
NOTE:
You noted ﬂow when aspirating from the waste tubing in step 2 of Section
4.2.3.
Raise the Sampler to the Syringe position. The Pump should be OFF for this test.
Connect a syringe of water to the reference electrode outlet port. Attempt to
inject the water.
If water ﬂows freely, air is entering the system preventing aspiration.
a. Inspect each electrode to assure the internal ﬁll solution level is not
dropping.
b. If yes, replace the electrode or membrane as required.
c. Inspect the seal between the reference electrode and sensor module
(interconnect tubing) .
If the ﬂow path starts to empty while the syringe is still
attached, only the water below the leak will leave the ﬂow
path out of the tip of the probe.
4-11
4. Trouble.
2.
If the reference ﬂow is obstructed, the sample may not
stop in the sensor module due to increased vacuum. Flow
time decreases due to increased ﬂow rate.
pHOx Service Manual
d.
5.
Inspect the sensor sealing washers for distortion or misalignment. Replace as necessary.
e. The seal between the air detector and the sample probe may be tested
by attaching the syringe to the sample probe, blocking the air detector
outlet tube. Apply pressure to the syringe and look for water leaking
out.
If water does not ﬂow freely, there is a blockage.
a. Loosen the reference electrode. Water should pass through or the
electrode is plugged. Flushing with cleaning agent or hot water may
free the blockage.
b. If the reference is clear, reinstall it and remove the bottom electrode.
c. Apply a moderate pressure with the syringe.
d. If water does not enter the sensor module of the bottom electrode the
blockage is above it.
e. Removing one electrode at a time. Look for water entering the sensor
module. If no water enters the module as the electrode is removed, the
plug is above it.
f.
If water did enter the bottom sensor module in step C above, the plug is
in the Sample Probe/Air detector. Remove these assemblies and ﬂush
through them or replace them.
4.2.3 Isolating a ﬂow problem between the Fluid Pack and the Fluid Fountain
If you have successfully aspirated a sample, but the analyzer will not calibrate or
aspirate on-board controls, proceed as follows.
1. Position the sampler in the syringe position and inspect the capillary adapter
for signs of wear. Replace if necessary.
2. Lower the sampler to the Home position; connect a syringe to the reference
outlet port.
3. Remove the analyzer cover.
4. Disconnect the S-Line (center tube) from the rotary valve.
5. Inject the water and look for ﬂow from the S-Line.
6. Look for a leak between the ﬂuid fountain and the capillary adapter. Realign
if necessary.
7. If there is no ﬂow from the S-Line, remove the ﬂuid fountain/S-Line and
ﬂush with hot water or cleaning agent, or replace the assembly.
8. If there is free ﬂow through the S-Line, the problem is in the rotary valve,
tubing harness, or connection to the ﬂuid pack.
9. Reconnect the S-Line and remove the ﬂuid pack.
10. Move the rotary valve to all the possible positions, observing which ports do
not allow ﬂow.
11. If there is no ﬂow in ALL positions, remove the valve and clean or replace it.
4-12
4 Troubleshooting
12. Remove the tubing for each position that does not ﬂow freely.
13. If water can be ﬂushed through the individual lines, remove and clean or
replace the valve.
14. If water cannot be ﬂushed through the affected lines, replace the tubing harness.

4.3.1 Analyte Troubleshooting ( Series code 1-6 and Digit codes 1-4)
Multiple Channel failures:
Slope
•
Ensure the Reagent Pack is fully plugged in.
•
The pack box edge closest to you should
lie inside the small lip of the chassis.
•
Check the ﬂow times displayed on the
service screens.
•
Inspect the Reference tubing to assure
ﬂow.
•
Inspect the waste line
for bubbles.
•
Prime the system,
check each ﬂuid for air.
•
pH and Na+ require
a working reference
electrode.
Figure 4-1 Reagent Pack Placement

•
•
•
Note if the channels that fail use the same standard from the ﬂuid pack.
Loss of the +5 Vdc on the analog board
Loss of the Analog board A/D/ converter
Loss of +5 Vdc to the Analog Board
Analog Board over heated (PTC resister open) - If unit is allowed to cool off
by shutting it off for 5 minutes. Investigate why the unit or Analog board is
overheating.
Dependency Rules
•
Hct requires calibrated Na+ for calibration and results.
•
PCO2 requires calibrated pH for results (pH checked on standards to assure
bicarbonate is correct).
•
SO2 requires calibrated Hct and PO2 for results. Calculated SO2% is reported if measured SO2 is not available.
•
Hb requires Hct and SO2 for reporting.
Priority:
1. If linked with COOX, the COOX HGB is reported.
2. If no COOX link, the measured result is reported, if available.
3. If no COOX or measured result, the calculated result from the Hct reading
(Hct/3) is reported.
4. If no COOX, no measured, and no Hct, the default value (Hb) is reported.

•
•
•
Qsp/Qt requires 2 separate blood samples for determination: mixed venous
and arterial.
RI utilizes input or default FIO2% for calculation.
Calculated Results require calibrated and proper results by measured tests
used in the calculation.
Suppression rules - If measured test is suppressed in the Setup, the calculated results based on test also will not be shown or printed.
Password (One) is used for Setup, Service Menu, and QC. (No user passwords are available.)
Interfaces are NOVA COOX, PDM, and ASTM.
Standby Mode:
There is no time dependency. Analyzer will prime and calibrate after coming
out of standby.
Idle pumping is active, but no ﬂuidic or gas calibrations are performed.
Features Auto-Wake-Up, Auto-Cal, and Auto-QC
Micro Sample Analysis:
Micro-Mode Tests: pH, PCO2, and PO2
Stepped Analysis: Stage 1 = Tip of probe to ADT1 (40 µL)
Stage 2 = Up to ADT3
Stage 3 = Between ADT3 (up to ADT4): Other Tests
Reading (including contact with reference electrode)
Instability
•
Inspect sensor module for bubbles during the measurement cycle
•
Ensure that the waste valve stops the ﬂuid ﬂow during analysis. Fill the ﬂow
path with any standard, raise the probe to the syringe position
Look for droplets forming at the sampler tip.
•
Ensure that the waste and Reference solenoid valve are functioning.
•
Fill the ﬂow path with any standard and view the system test screen.
The signals should be steady and there is no ﬂow of ﬂuid there are three
Possible conditions, a loose sensor module, an analog board failure, or a
poor connection between a set of electrodes and an interconnect board.
•
Inspect the electrode washers to assure proper alignment. Nonalignment
may cause a ﬂow problem.
•
In rare cases the tubing harness may have become contaminated. Using the cleaning adapter, ﬂush the system with cleaning agent followed by distilled water.
4-19
4. Trouble.
•
P50 is measured and is reported only when PO2 is between 30-75 mmHg.
P50c is reported when PO2 is outside those limits. P50 also requires calibrated SO2% and Hb/Hct for reporting.
pHOx Service Manual
4.3.2 Single Channel Failures
Slope
View the Sensor Subsystem screens. If the change in millivolts between standards
is 0 or less than that mentioned in Section 4.3.1, there are several possibilities:
•
Membrane or sensor has reached the end of its use life.
•
Bubble of Air is covering the sensing material at the electrode tip.
•
The electrode is not making good contact with the Interconnect board contacts.
•
Loss of the Analog board multiplexer will cause a zero input to the A/D converter.
•
Ensure calibration on required channels: Sodium is required for Hct, Hct is
required for SO2%.
•
Viewing the Sensor subsystem screens you note an overload condition (999.9 mv).
•
Check for NO connection to the Interconnect board.
•
Check the PO2 /PCO2 for loss of the Internal Fill solution (membrane rupture).
•
Loss of the multiplexer or individual channel circuit on the Analog board.
•
The pH electrode may need conditioning.
•
Na+ sensor over 30 days of use. The Na+ sensor will be destroyed by conditioning.
Instability
Single channel instability is seldom a ﬂow problem unless a standard is unique to a
particular channel.
•
De-bubble the electrodes.
•
Ensure a good connection between the electrode and the Interconnect
Board.
•
Ensure a good connection between the sensor module and Chassis.
•
Ensure the analyzer's door is closed and the ground strap is making good
connection.

4 Troubleshooting
4.3.3 Temperature Problems
•
•
•
•
•
Ensure that the room ambient temperature is within speciﬁcation ( 18o - 32o C).
Ensure that the sensor module is plugged in correctly.
View the Analog Input screen channel 20. This channel will be a 0 if the
module is at 37o C and change at a rate of 22.5 mv/1oC, + if above and - if
below 37o C.
The power for the preheater comes from the digital control board.
The heater control circuitry is on the analog board.
4.3.4 Air Detector (ADT) Problems
•
•
•
NOTE:
•
•
Air Detectors are only calibrated during a 2-point calibration.
Typically the Fluid /Air millivolt difference will be about 700.
Check the sample probe for air being introduced below the sensor module.
Check the sensor module for air being introduced at the electrode/sensor
module seal.
Ensure that the electrode sealing washers are centered and seated correctly.
The Air detector signals are processed by the analog board. They are only
displayed on the System Test screen. Alternately aspirate air and then ﬂuid
to see the change in the signal.
Remember to turn on the air oscillator to obtain an ADT reading.
Flow Test
During a ﬂow test, the rotary valve rotates to each ﬂuid position.
The pump turns on to ﬁll the lines from the rotary valve S-line port to
the ADT1.
The rotary valve rotates to an air position.
The pump turns on and the time in milliseconds until the ADT senses
air is recorded.
The time is normally 1200 msec. The acceptable range is 100 to 1700
milliseconds.
Run a Flow Test; press the soft key on the Service screen.
Typical result for Standard A, B, C, D is 1300.
If all are high (3000-5000), there is a ﬂow path obstruction.
If only one is high,
1. Check for correct ﬂuid pack installation.
2. Check that the valve is in the correct position.
3. Connect a syringe to the S-line port of the valve. Remove the
reagent pack and move the valve to each position. Verify that the
link is clear by purging air through the S-port.

Shutdown Procedure
If the analyzer is to be turned off for more than 24 hours, ﬂush the tubing harness ﬁrst with
distilled water then with air. Use the Flush Fixture (PN 24327) to perform this procedure.
1. Remove the Reagent Pack from the analyzer.
2. Install the Flush Fixture into the analyzer in the same way as the Reagent
Pack.
3. Place the W-line of the ﬁxture into an empty container.
4. Place the other tubing ends into a beaker of distilled water.
5. From the Ready/Not Ready screen, press Menu (soft key).
6. Select Flowpath Maintenance and press Enter.
7. Press Purge (soft key).
8. When the cycle ends, take all the tubings out of the distilled water. Leave
the W-line in its container.
9. Repeat the purge with air.
10. When this cycle is completed, remove the ﬂush ﬁxture.
11. The pHOx Analyzer is now ready to be powered off for extended time.
