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-

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.

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.

display and, beneath it, the percentage deviation and the average flow velocity of the pump
stroke.
