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.

CHANGE to select a value between -10 dB SPL to 5 dB
SPL or to set it OFF.

The CLOCK MODE menu allows the user to change the clock
from a 24 hour mode to a 12 hour mode (Figure 61).
 
CHANGE to select 12 Hour or 24 Hour.

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.
