Quality tests
Damage or malfunction of the Otoport, the probe or the cables can lead to
errors in testing. To ensure that any faults are detected before they lead to
faulty data collection, the following tests can be performed.
Quality tests should be carried out on a weekly basis.
There are five different quality tests, described below. The Probe Test
and ABR Cable Test are initiated from within the Configuration menu; the
Cavity, Occlusion and Real Ear tests involve running a standard TEOAE or
DPOAE test.
14.1
Probe test
Probe Test is an option accessed from the configuration menu (see
chapter
11
Configuration ).
A Probe Test should be performed regularly to monitor the calibration of
the probe’s output stimulus level and microphone response.
Note:
Probes supplied with a new Otoport system are tested with the
system and Probe Test levels are stored. These levels form a
baseline to compare future tests against in order to monitor any
calibration drift. It is not necessary to save a new baseline level
for these probes.
