Description
USE SCENARIOS
- Primary open-circuit pressure sensitivity calibration of laboratory standard microphones
- Measurements according to IEC 61094-2 on IEC 61094-1 microphone types:
- LS1P (for example, Type 4160)
- LS2aP (for example, Type 4180)
- Measurement of static pressure coefficient using integral pressure chamber
CALIBRATION SYSTEM FEATURES
- Fast PC-controlled determination of electrical transfer impedance
- Measurement and calibration data stored on disk or printed as hard copy
- Frequency range: 20Hz to 10kHz (LS1), 20Hz to 20kHz (LS2)
- Unique vibration and ambient noise damped microphone mounting stand
- Dimensionally stable plane-wave sapphire couplers
The system can work in a ‘normal’ laboratory environment with no specific precautions with respect to background noise and vibration.
