5.10.2.6 Minimum Value (MIN VALUE)
Figure 60
With the MIN VALUE setting (Figure 60) the user is allowed to
include the minimum OAE response amplitude to the
PASS/REFER criterion for a single frequency. When the MIN
VALUE setting is set between -10 dB SPL and + 5 dB SPL the
OAE response for the frequency under test needs to be at an
equal or higher level than the MIN VALUE set to get a PASS
result. If MIN VALUE is set to OFF, the PASS decision is based
on the SNR alone for the current frequency measured.
Default MIN VALUE setting is -10 dB SPL.

The
CLOCK MODE
menu allows the user to change the clock
from a 24 hour mode to a 12 hour mode (Figure 61).

5.10.2.8 Graph Style
Figure 62
The user can select between two options of displaying the result.
(Figure 62). The SNR graph displays the Signal-to-noise ratio as
a function of frequency. The value graph view shows absolute
OAE levels and noise levels as a function of frequency.
