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
The calibration is factory set and should remain stable indefinitely.
The calibration may be checked and altered, however, by connecting
the device via the Pressure Calibration Kit (36-ASS1234) to a Water
Manometer, as shown below:

Slide the MicroRPM switch from 'Off' to 'SNIP' whilst applying no
pressure to the unit.
Gently fill the syringe until negative pressure of between 200 and
300cmH2O is read on the Water Manometer. Check that the reading
on the MicroRPM is within 3% of this reading.
