MENU 03 DB SCALE SELECT
dB Select has two settings from which to choose. These settings will determine the baseline dB
reference level of the instrument. Once selected, all test results will be based on the selected
baseline dB level.
THERE ARE TWO SCALES: RELATIVE AND dB OFFSET
Relative
sets the instrument to the 0 dB of the instrument’s internal minimal detection value
and is the factory default setting.
dB offset
is a dB level that is a new minimum reference level set by the user. This value may
be any dB level above the natural 0 dB of the instrument. Once set, the preset level must be
subtracted from the reading to determine an accurate dB increase. (EG: if “10” is the dB offset
value and a subsequent reading is 25 dB, then the increase is 15 dB.)
TO SELECT A dB REFERENCE SCALE
Make sure the Ultraprobe is off.
Press (click) both the yellow Store button and the Sensitivity dial at the same time, then
squeeze and hold the trigger.
