When the unit is ready for use 0 will be displayed.
To perform a SNIP test instruct the subject to insert the nasal probe
into a nostril such that a good seal is made. After a normal expiration
they should inhale with as much effort as possible through the free
nostril with the mouth closed. The manoeuvre is performed from
functional residual volume (FRC). The reading displayed is the peak
inspiratory nasal pressure.
Before repeating the measurement, the instrument must be reset by
sliding the switch to the "off" position.

Switching Off

The MicroRPM is switched off by sliding the switch back to the 'Off'
position.

Battery Low Voltage Indication

The battery level is checked when the unit is switched on.
When the battery is nearly exhausted 'bAt' is displayed before the
auto-zero procedure begins. The unit may be used when this occurs
provided the test is performed immediately. The battery should be
replaced as soon as possible.
When the battery is completely exhausted the unit will beep twice and
turn itself off immediately after turning on.
Note: If the respiratory pressure meter is not used for long periods,
the battery should be removed to prevent damage to the instrument
by possible leakage.
