3.5.7 Start
and stop of a tympanometric test
After startup the AT235 is ready to automatically start a measurement as soon as it detects that the probe is
in the ear. When the probe is in the ear the test can be manually stopped (or paused) and again started by
pressing the “Start/stop” button (22) or by pressing the probe button. When the probe is out of the ear the
test can be stopped (as if it is paused before inserting the probe) or started by pressing the “Start/Stop”
button (22). Using the probe button while the probe is out of ear will result in changing the selected ear side
and at the same time restoring the automatic start function if necessary.
