Starting the test
1. Use the dial to adjust the desired start pressure.
2. Press the
Start/Stop
button to initiate the test.
3. Use the dial to control the pump and create a manual tympanogram.
The derived measurement data in the tympanometric results table are calculated from the baseline reference data at
200 daPa. The results table accordingly remains empty, and the curve remains non-baseline compensated until you
have reached 200 daPa.
4. Press Stop to finish the measurement.
5. When you have finished testing one ear, switch ears, if needed.
