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, pre- and 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 1-2-5 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.

13 EasyOne-CS Lithium Battery Replacement
This procedure is intended for use by trained electronic service technicians. It describes how to 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.
2030434-006 Rev. D EasyOne-CS Field Service Manual Page 21
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.

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
2030434-006 Rev. D EasyOne-CS Field Service Manual Page 22
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)
False Correct
2030434-006 Rev. D EasyOne-CS Field Service Manual Page 23
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.
2030434-006 Rev. D EasyOne-CS Field Service Manual Page 24
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
