Calibrating test box reference microphone

Remove any coupler from the coupler microphone before calibration.

1. Position the test box reference microphone opening concentric with the coupler microphone opening and

about 1 – 2 mm from as shown below.

2. Close and seal the test chamber.

3. Press <Tests>, then highlight and <PICK> [Test box measures], then highlight and <PICK> [Calibration].

4. Highlight, then <PICK> [Daily] or [Weekly] to select the calibration interval.

5. Highlight and <PICK> [Calibrate]. See Test box calibration facts

It is recommended that you print a copy of the initial calibration curve and compare it with your daily or weekly

curve. Any change in this curve indicates a drift in either the coupler or the reference microphone which needs

further investigation. See Calibration check for coupler microphone for an additional check.
