MENU 29: dB SCALE TYPE SELECT (RELATIVE OR OFFSET)
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.)
