Overview

The CR516 Acoustic Calibrator meets ANSI S1.40:2006 and IEC 60942:2003 to Class 2. It is designed for use with the Class 2 sound level meters and noise dosimeters that NoiseMeters offers.

Hand held sound level meters generally expect a calibration level of 94 dB at a frequency of 1 kHz. Noise dosimeters, which mount on a worker's shoulder to monitor daily noise exposure levels, often expect a calibration level of 114 dB at 1 kHz. Rather than having two calibrators the CR516 can be switched on at either 94 dB or 114 dB for use with either noise measurement device.

Using It

When the Calibrator is switched on it emits a 1 kHz tone at either 94 dB or 114 dB. The calibrator should be pushed carefully (firmly, but slowly) on to the microphone capsule of the sound level meter or noise dosimeter.

The meter should now be adjusted accordingly. Older sound level meters will have to be adjusted manually to the correct reading. Most modern meters (and all those supplied by NoiseMeters) adjust themselves automatically.
