AWA6021A sound calibrator is mainly used for the sensitivity calibration of measuring microphones
and acoustic measuring equipment. It is small, light, stable, easy to operate, and has automatic
air pressure compensation. Its performance complies with technical requirements for class 1
sound calibrator of GB/T 15173-2010 and IEC 60942: 2017.
Remark:AWA6221A is no longer in production, alternative model is AWA6021A
Operating method
Press and hold the ON/OFF button on the
calibrator for 1s and release it. The calibrator starts
generating sound, the red starts flashing. Then, set the
plummet of the calibrator on the microphone under
test and keep stable. When the red indicator in the
calibrator button stops flashing, it indicates the sound
pressure level in the calibrator is kept stable at 94.0
dB.
Use of the sound pressure level of 114.0 dB
When the red indicator in the calibrator stops
flashing, again press and hold the button “94/114” on
the calibrator for 1s and release it. The green indicator
in the button is on and then the red indicator starts
flashing. When the indicator stops flashing, it
indicates the sound pressure level in the calibrator is
kept stable at 114.0 dB. Press the ON/OFF button
again and the calibrator is switched off.
