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