Quality checks
The probe outputs sound at 1, 2 and 4kHz for both loudspeakers in the
DP probe (
A
and
B
) and the system compares the response at these
frequencies against values already stored on the probe.
Checking the probe response against the absolute range determines if
the probe is OK for use. Checking the probe response against the probe
specific values is more sensitive and provides a warning if the response of
the probe has changed.

Results
The possible results of the test are:
Pass
The levels recorded at all frequencies are within the absolute range and
within ± 3dB of the probe specific values.
Fail
One or more of the levels recorded are outside the absolute range
specified for the probe. If a Fail is shown on screen inspect the probe
coupler tubes for debris, replace the coupler if necessary and repeat the
Probe Test, by selecting
Retest
, ensuring the ear piece is firmly inserted
in the test cavity. If the test continues to fail there may be a fault with the
probe or system. Contact your dealer or Otodynamics for advice.
