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.
