1470_dis

Calibrator adaptor for use with 1″ calibrator or pistonphone for calibrating the outdoor microphone Nor1210 C version with serial numbers higher than 15177.

Microphones with serial numbers lower than 15177 should use Calibrator Adaptor Nor1470.

It is recommended to use calibrator Nor1253/250Hz-124dB for calibration, since this calibrator is less sensitive to changes in load volume compared to a pistonphone or a traditional calibrator.
