SOUND CALIBRATION

8. Press UNIT to save the calibration

data, exit Calibration Mode, and
resume measurement.

9. To calibrate the Sound-Level meter to

a second set-point (114 dB), set the
Acoustical Calibrator to 114 dB and
repeat steps 4 through 7.

Note…
The 114 dB calibration point displays as a
double-digit decimal instead of the full
value (i.e., 13.8 instead of 113.8).
