Minimum Amplitude
The Minimum Amplitude setting allows the user to set the unit
to include minimum amplitude values in the pass/refer criterion
(Display 23). The ERO•SCAN
®
is set with this feature turned OFF
when it is shipped from the factory. If the MIN VALUE is set to
“ON”, a result is not considered a pass unless the amplitude at
each frequency is equal to or greater than the minimum value
programmed into the unit. This is in addition to meeting the
other pass criteria including the minimum SNR and the number
of passing frequencies for overall test “Pass”.
To change the mode to Minimum Amplitude setting, press the
LEFT or RIGHT
arrow keys to make a selection. Once you
have made your selection, press
NEXT.
The minimum DP amplitude when ON is -5 dB SPL.
The minimum TE amplitude selections are -5 dB SPL. and -10
dB SPL.
