Configuration
Freq range
The frequency range tested may be selected with the left and right arrow
keys.
1.5-8k tests at six F2 frequencies: 1.5, 2, 3, 4, 6 and 8kHz
1-6k tests at six F2 frequencies: 1, 1.5, 2, 3, 4 and 6kHz
2-6k tests at four F2 frequencies: 2, 3, 4 and 6kHz
The frequency range for DP 12 Freq is fixed at 1-8kHz.
Start
With start mode set to
On
(default), the testing will proceed from
Checkfit
to
Test
as soon as the Otoport detects a stable probe fit, without the need
for the user to select
Start
.
With the
Start
setting
Off
, the user must initiate the test by selecting
Start
when the probe fit and test conditions are satisfactory.
Irrespective of the
Start
setting, the
Start
button is available in order that
the user can initiate a test.
Stop
The
Stop
setting controls whether the test automatically stops when the
pass criteria are met. If
Stop
is turned
Off
,
the test will run for longer, but
the OAE levels will be more accurately measured. If
Stop
is
On
when
screening, the test will be as short as possible.
Band SNR
Band SNR
sets the minimum Signal to Noise Ratio required in each band
before that band passes. The SNR calculated is dependent on the noise
mode used (see
15.2.1
Noise mode
).
By default, it is set to 6dB SNR.
