5.2 Calibration

It is important to calibrate each dBadge before and after use, in

accordance with workplace noise regulations. The dBadge records

calibration levels and times which can be viewed later on dB35

software.

Note that the dBadge will not enter calibration mode if a

measurement run is taking place. If a run is in progress, stop the

run according to section 5.4.

The windshield should be removed prior to calibration, refer to

section 3.4.

Push the CEL-110/2 acoustic calibrator over the microphone as

shown in Figure 11. The calibrator should be pushed on without

twisting.

Figure 11

The CEL-35X dBadge will automatically recognise a 1kHz

calibration tone is present and display the screen shown in Figure

12.
