The ultrasonic sensor of EasyOne Air does not require calibration. Only
unforeseeable reasons can lead to a malfunction that affects results. In these
cases, you can determine whether EasyOne Air operates normally with a
simple calibration check. Therefore, a regular calibration check is
recommended to ensure the reliability of the tests. The American Thoracic
Society (ATS) recommends that calibration must be checked periodically.
For criteria for acceptable trials, refer to the previous chapter.

1 To assure that the temperature inside the syringe and the room
temperature are the same, push and draw the piston five times.
A temperature difference may lead to a failed calibration check.
Do not warm the body of the calibration syringe with your hands.
2 Push the piston of the calibration syringe all the way in.
3 Unwrap the EasyOne Flow Tube.
4 Insert the EasyOne Flow Tube into EasyOne Air.
The shape of the EasyOne Flow Tube and the EasyOne Flow Tube holder
guide the orientation of the EasyOne Flow Tube. You can only insert the
EasyOne Flow Tube fully if it is positioned correctly.
5 Attach the EasyOne Flow Tube cal check adapter to the calibration syringe.
To avoid any temperature differences, fixate the syringe with two
fingers at the one end of the syringe only.
6 Attach the nozzle of the EasyOne Flow Tube cal check adapter to the
EasyOne Flow Tube and make sure that the piston is fully inserted.
The EasyOne Flow Tube snaps into the nozzle of the EasyOne Flow Tube cal
check adapter.
