Remark : The above spec. are tested under the environment RF Field Strength less
than 3 V/M & frequency less than 30 MHz only.
Frequency Weighting Network
Characteristics of A & C.
A weighting : The characteristic is simulated as "Human Ear Listing"
response. Typical, if making the environmental sound level measurement, always select to A weighting.
C weighting : The characteristic is near the "FLAT" response. Typical, it is suitable for
checking the noise of machinery (Q.C. check) & knowing the sound pressure
level of the tested equipment.
Data hold To freeze the measurement value.
Peak hold To keep the peak ( max. ) measurement value.
Time weighting (Fast & Slow)
Fast - t= 200 ms
* "Fast" range is simulated the human ear response time weighting.
Slow - t = 500 ms
* "Slow" range is easy to get the average values of vibration sound level.
Range selector
Auto range : 30 to 130 dB.
Manual range : 3 range, 30 to 80 dB, 50 to 100 dB,
80 to 130 dB, 50 dB on each step,with over & under range indicating.
Frequency 31.5 to 16 KHz.
Microphone type Electric condenser microphone.
Microphone size Out size, 12.7 mm DIA. ( 1/2 inch).
Calibration VR
Build in external calibration VR, easy to calibrate on 94 dB level by screw driver.
* Calibrated via external SOUND CALIBRATOR ( SC-941, optional ).
Calibrator B & K (Bruel & kjaer), Multifunction Acoustic Calibrator 4226.
