Definitions for acoustic metrics such as LAeq and LAVG are provided.
The MODEL 22 and MODEL 22R comply with IEC and ANSI standards, with a measurement range of 70dB(A) to 130dB(A) RMS.
The dosemeter supports dual-channel measurements, storing various data including configuration and calibration records.
- LEP,d: Average of measured Leq over eight hours.
- LEX,8h: EU term for Daily Personal Noise Level.
- TWA: Time Weighted Average over eight hours.
- % Dose: Percentage of a fixed dose value.
- Estimated Dose: Projected % dose for the criterion time.
- Exposure: Noise exposure in linear terms.
- LAE or SEL: Sound energy level equivalent to one second of constant noise.
Calibration is crucial for accuracy, with offsets automatically applied.
Operating temperature ranges from -10°C to +50°C, with storage up to +60°C.
Measurement kits are available with different numbers of dosemeters.
Stabilize temperature, pressure, and humidity before calibration.
Charge, rest, calibrate, measure, and recharge the dosemeter for stability.
Instructions for resetting the dosemeter and Reader are provided.
