2.5 Calibration cavities
You can use the 0.2 ml, 0.5 ml, 2.0ml and 5 ml for validity check of the probe calibration.
To perform a calibration check, select a protocol the measures a tympanogram.
Do not use an ear tip! Place the probe tip completely into the cavity. Perform the measurement. Check the
volume that was measured.
The allowed tolerance in the volume measurement is ±0.1 ml for cavities up to 2 ml and ±5% for larger
cavities. These tolerances are applicable for all probe tone frequencies.
We strongly recommend calibrating probe and contra phone at least once a year.
