2 Intended Audience
This manual is intended for the person who uses, maintains, or troubleshoots this equipment.
3 Introduction
The EasyOne-CS Spirometer uses digital ultrasonic flow measurement technology for fast, accurate,
reliable operation. The EasyOne-CS was designed for full range testing in primary care, specialty
physician, industrial and hospital settings. It offers automated comparison to predicted values, preand post Broncho Dilator comparisons, interpretation of results and test quality control that
automatically assesses patient effort offering helpful suggestions to obtain optimum results. Optional
easy to read and interpret color printout with graphic display for instant test review is available. The
single-patient-use spirette minimizes risk of cross-infection.
4 Operation Principle
This EasyOne-CS flow sensor is equipped with two ultrasonic transducers, mounted at different sides of
the flow channel. In order to determine gas flow (and molar mass), ultrasonic pulses are transmitted in
up- and downstream direction. Precisely measured transit-times are the basis for determining flow and
molar mass. The following figure shows a diagram of the flow sensor including its internal sound
transmission path.

8 Checkout Procedure
After repair or maintenance of the EasyOne-CS the following procedure is recommended in order to
check correct operations of EasyOne-CS:




Optional step: If all data in EasyOne-CS must be deleted, perform the ‘hidden key’ sequence 12-5 described in the following chapter in order to perform a factory reset. Please be aware that
this step clears all customer data and resets the device to factory default settings.
Get a calibration adapter and a calibration syringe (2030431-010)
Ensure that the correct syringe volume is entered in the instrument’s configuration setting.
Choose item “Check calibration” in the main menu of EasyOne.
2030434-006 Rev. D
EasyOne-CS Field Service Manual
Page 13

Connect the spirometer as shown below using the calibration adapter and the syringe. Ensure
that the piston is fully inserted and at the stop position.



Now press ENTER.
Wait until the baseline has been set and you hear an audible signal.
Now execute one full inspiratory pump stroke followed by one full expiratory pump stroke at
moderate speed.
After you perform the maneuver, you will see the text "Accuracy confirmed" at the top of the
display and, beneath it, the percentage deviation and the average flow velocity of the pump
stroke.
If desired, make a printout of the calibration report.

exchange the internal Lithium battery.
13.1 Background
The internal Lithium battery of the EasOne-CS has a lifetime of more than 5 years (designed to last up
to 10 years). If the lithium battery is empty, the device shows an error #25 message. The battery is
needed to hold the date & time and parts of the device configuration information which is stored in the
RAM area of the RTC. If the battery is empty, this data is corrupt and leads to the above error. In this
case, it is necessary to change this battery.

13.2 Environment
1. Windows PC with installed and working EasyOne-CS connection (Serial cradle, USB cradle or
Screen-Connector)
2. Installed EasyWare greater or equal V02.04
3. Torx T8 / Allen key /hex key screw driver depending on serial number
4. Electrostatic save working environment for the device disassembly
13.3 Preparation (save database)
To make sure that no data is lost/altered, the internal EasyOne-CS database should be saved first.
Please follow the below steps.
1. Start EasyWare by the link on the desktop
2.
Switch EasyOne-CS on and press key sequence 1-3-5 when the below shown error screen
appears. Enter the date & time if requested. Then the normal main menu should be shown.
ERROR
Device Selftest
Error #25
Please contact
service
3. Connect the EasyOne-CS to the PC (Device Connected is shown in the status line of EasyWare/
“PC interface active” on the EasyOne-CS screen)
4. Go to menu: File/Backup Device DB… And the following progress bar appears
5. The EasyOne-CS backup file will be written (takes several minutes) and the success is indicated
by the following dialog
6. The backup file of the form EZ1BackupXXXXX_DateTime.txt
- XXXXX: device serial number
- Date: YearMonthDay
-Time: HourMinute
(e.g. EZ1Backup40126_200506071607.txt) is located in the folder where EasyWare has been
started e.g. C:\programmfiles\ndd Medizintechnik\EasyWare

13.4 Battery exchange procedure
Please make sure that your working environment is electrostatic safe to avoid damage to the used
electrostatic sensitive electronic components




Open the front cover by removing the two main screws.
Remove the printed circuit board (PCB)
Do not remove the sensor tube (two additional screws)
Remove the Lithium battery (see figures below)

Insert only 3V BR 1225 batteries which are approved by ndd Medizintechnik AG (e.g. Panasonic
3V BR 1225)
Make sure that the + Sign form holder and battery are matched.



Enter the new battery by preventing any short circuit (use only your fingers)
Insert the PCB back to the EasyOne-CS case.
Attach the front half of the case (make sure no cable will be squeezed)

13.5 Restart EasyOne-CS
Switch the EasyOne-CS back on. The above described error screen (#25) should be shown. Do the steps
as described before. If you are in the main menu, check that all records are there by going to View
results. If you are sure that all records are there, the exchange is finished.
13.6 Restore database
Under normal conditions EasyOne-CS restores the database by it self (Please wait… screen after 1-3-5).
Double-check the amount of stored records. If the “Please wait…” screen appears longer than ca. 3
minutes you can interrupt it by pressing the ESC key (hold 0 key for more than 2sec.). This is only
possible for firmware versions >= V02.14.00.00. If restore database failed, it will be necessary to
restore the database manually. This can only be done at ndd!
14 EasyOne-CS board with sensor and housing parts Replacement
This procedure is intended for use by trained electronic service technicians. It describes how to
exchange the internal board with sensor and how to change the housing parts.
14.1 Background
If the sensors and/or the board fail, the complete board with the sensors has to be changed. If one
housing part gets disturbed, change it following the description.
Please make sure that your working environment is electrostatic safe to avoid damage to the used
electrostatic sensitive electronic components
 Open the battery door and remove the 2 AA batteries
 Open the front cover by removing the two main screws on the backside

Remove the board (no screws) so you can remove the sensor tube by removing the two screws

When you only change the front you must not remove the board with the sensors, remove the
keypad from the damaged front and put it into the new front part.

When you change the board, remove the old one and replace it with the new one. Bring the
sensor tube into position and screw it with the washers – be carefully, do not turn the screws to
tight! Bring the board into position.

Put the front part with the keyboard back on the instrument in that way that the window is
placed over the LCD display and that the front fits tight on the back cover
Turn the instruments (front at the bottom) and turn the screws in. The holes in the hook sleeves
must be in the right position, look to the left and right side of the instrument

When you change the rear half of the housing, please remove the pocket and the serial number
label (silver label) from the old housing part and but the pocket into the rear half and glue the
label at the same position on the new rear half part.

When you change the board with sensor, remove the old label and glue the new delivered one
onto the rear half.
Put in the 2 AA batteries, close the battery door
