The ultrasonic sensor of EasyOne Pro/LAB does not require calibration. Only
unforeseeable reasons can lead to a malfunction that affects results. In these
cases, you can determine whether EasyOne Pro/LAB 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.
If you do not reach ±3.5% accuracy, troubleshoot. If you are not able to
remedy the defect, contact your EasyOne dealer or the ndd Servicing
Department.
1 Unwrap the spirette.
2 Insert the spirette into the flow sensor.
 The shape of the spirette and the spirette holder guide the orientation
of the spirette. You can only insert the spirette if it is in the correct
orientation.
3 Attach the spirette 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.
