You can record a tympanogram either as a separate measurement or as part of a diagnostic or screening sequence. In a
sequence, tympanometry is automatically followed by reflex testing.
In the following you will find the description for performing tympanometry as a single test. This means that the sequence
function is not enabled.
The default setup available in the tympanometry test is designed for any of the tympanometry tests you can
perform. Adjust the settings to suit your purposes.
Preparing for testing
1. Do as described in
