better) to match the model of your SoundCHEK Essential sound level meter.

keys. Only include the microphone-
dependent pressure to free field correction in this calibration adjustment.
Ensure the calibrator is attached to the microphone by gently inserting the microphone into the
cavity of the calibrator. A certain amount of resistance should be felt while inserting the
microphone as the O-ring on the calibrator forms a seal around the microphone. Switch the
calibrator on and set to the required output level.
