supplied with the instrument.

Wait until “INSERT PROBE” is displayed.
Insert the probe, without an ear tip, into the hole at the 2ml end of the test cavity. Make sure
that the probe is pushed fully home and is held tight against the stop. The probe must be square
to the end of the test cavity.
When measured at elevations below 1,000 ft, the display should show the volume of the 2ml test
cavity to within ± 0.1ml.
