Technical characteristics of acoustic instruments calibrators CAL200:
 
Precision Acoustic Calibrator CAL200 company Larson-Davis used to calibrate the apparatus shumoizmeritelnoy.
The calibrator produces a fixed sound pressure level at a frequency of 1 kHz.
Signal Level Acoustic Calibrator CAL200 device can be switched between the values ​​of 94.0 dB and 114.0 dB.
The device has a slot for a half-inch microphones, and with the appropriate adapters can be used with 1/4 inch and 3/8 inch microphones.
Power to the device is an acoustic calibrator CAL200 by 9V battery (for example, type "crown").
In the case of low battery level and frequency of the calibration signal is not changed, but the duration of the signal decreases (normal - 60 seconds after pressing).
