Note: Calibration should only be attempted if a 94dB calibrator is available. Attempting a calibration without a calibrator on the microphone will result in a complete decalibration of the instrument. When that occurs the factory must be contacted to provide the instrument’s original calibration file.

 

The instrument can be field-calibrated using a 94 dB calibrator with a standard 1/2” opening.

 

Field calibration is performed by the Instrument_Manager application. Follow these steps:

1. Remove the wind-screen

2. Place the instrument’s microphone in the calibrator

3. Start the calibrator

4. Press the Calibrate button on the application window and follow the on-screen instructions.

The calibration button can also be used to recall the factory calibration in case it is lost, or the instrument is decalibrated by mistake.
