Calibration – Noise Dosimeters
About
Noise dosimeter calibration. Measurement method in accordance with PN-EN 61252, including indication of:
• absolute acoustic sensitivity
• errors in the frequency correction
• frequency correction characteristics by means of a coupler, electrostatic actuator or a multi-frequency calibrator
• linearity errors in response to a change in the level of the sinusoidal input signal
• linearity errors in response to a change in the integration time
• errors of dosimeter response to short-term signals
• the difference of the dosimeter's response to pulses of the same polarity
• overload indicator with a hold
Advantages: short service time due to automation of measurements.
