Secondary Calibration System designed for calibration of working standard microphones and other types of microphone.
Type 9721-A
Type 9721-A Secondary Calibration System applies the comparison method for sensitivity calibration and the electrostatic actuator method for frequency response calibration.
Type 9721-A is a general-purpose microphone calibration system for calibration of working standard microphones described in IEC 61094-4, laboratory standard microphones described in IEC 61094-1 and other non-standard microphones. The system is intended for calibration service centres and owners of large amounts of microphones. The sensitivity of the microphone is measured by the pressure comparison method described in IEC 61094-5 and the frequency response is measured by the electrostatic actuator method described in IEC 61094-6.
