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.

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
