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).
