Calibration
Select Calibration to acoustically calibrate your SONIK sound level meter.
It is recommended that the calibration procedure is undertaken prior to, and after
measurements have been taken using either the Castle GA607/GA601 acoustic
calibrator, depending on the class of your instrument.
Cal Value (dB)
Adjust the Cal Value (dB) between 91.0 and 120.0 dB in 0.1 dB steps using the
Left
or
Right
Arrow
keys or 1dB steps using the
Up
or
Down
Arrow
keys. Include both
atmospheric pressure and microphone dependant pressure to free field corrections
in the Cal Value.
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 whilst inserting the microphone as the O-ring on the calibrator forms a seal
around the microphone. Ensure that the calibrator is switched on and set to the
required output level.
When the Cal Value is set correctly, including corrections, press
OK
to begin
calibrating your SONIK sound meter.
