Important note: Used mouthpieces and Nasal Probes, which are not
sterilized, must be disposed off immediately after each use.
If there are changes on the material surfaces (cracks, brittleness) the
respective parts must be disposed off.
Calibration
Calibration is factory set and should remain stable indefinitely.
However, calibration may be checked by connecting the device to a
manometer as shown below:

Turn the respiratory pressure meter on to the SNIP position.
Very slowly fill the syringe until a negative pressure of between 200
and 300cm is obtained on the manometer.
Check that the reading on the respiratory pressure meter is within 3%
of the manometer reading.
