21.1.3 Resetting your doseBadge
Your doseBadge can be reset using the small button on the underside of the instrument
as shown below. This will reboot the instrument; any stored measurements will not be
affected.
If your doseBadge is reset using the reset Button, ensure that the unit is awake by gently
shaking the instrument. The green status LED will flash to show that the instrument is
awake and ready for use.
21.1.4 Calibration failure
The doseBadge5 is pre-programmed to accept a calibration level that is provided by an
acoustic calibrator.
If the level provided by the acoustic calibrator is different from the level that the instrument
is expecting by more than +/- 3dB, the instrument will not start the calibration process. This
will not show as a failure, rather the instrument will simply not calibrate.
If the calibration level is /- 3dB of the expected value but is unstable, for example if
the background noise if too high and is affecting the calibration level, your doseBadge will
show a calibration error with a solid red LED for 5 seconds.
The most likely causes of a calibration failure are:
1. The level being provided by the acoustic calibrator is incorrect
• Check the level of the calibrator matches that of the doseBadge5
• Check that the expected calibration level programmed into the doseBadge5 matches
the acoustic calibrator
2. The background noise is affecting the stability of the calibration level
• Move to a quieter location and retry the calibration process
To check or adjust the expected calibration level that is programmed into the doseBadge5:
1. Connect the doseBadge5 to the NoiseTools software via the Dock
