Quality tests
Damage or malfunction of the Otocheck, 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.
The quality tests are described below. The Probe Test and ABR Cable Test
are initiated from within the
Configuration
menu.
13.1
Probe test
Probe Test
is an option accessed from the configuration menu (see
chapter
10
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 Otocheck 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.
Replacement probes supplied should be tested with your
Otocheck system and new Probe Test results saved as a
baseline reference.
