Menu 31: 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 read-
ing is 25 dB, then the increase is 15 dB.)
To select a dB reference scale:
1. Enter the Setup Mode
2. Spin to dB Scale Select (Menu 31 blinks).
3. Click in the Sensitivity Control Dial.
4. Spin the Sensitivity Control Dial to the desired scale (Relative or Offset).
5. Click the Sensitivity Control Dial to set.
6. Press the Yellow ENTER button to exit.
