Calibration - Vyaire MicroRPM Operating Manual

PeraSafe (36-SSC5000A). Rinse thoroughly and leave to dry before
reassembly.
Important note: 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.
