Preparations
5. Use the supplied miniature screwdriver to adjust the calibration control on the side
of the unit so that the level reading is 94.0 dB.
6. Press the CAL key once more to return to the measurement screen.
Note
The calibration control is a multi-turn type. The value may
not change on a single turn.
If a measurement is currently in progress (indicated by the
"measurement in progress" triangle or the "pause" mark), or
if a menu screen is currently shown, calibration cannot be
carried out. Wait until the measurement is completed (or
press the START/STOP key), or terminate the menu screen
before initiating calibration.
