IEC61672,Class 2

Measured and evaluated items Lp (time weighted sound level) or Lmax (maximum time weighted sound level), Lmin (minimum time weighted sound level), LCpeak (C weighted peak sound level).

Microphone:

Class 2 industrial measurement microphone, nominal diameter 12.7 mm, free field type frequency response. Nominal pressure sensitivity is 50 mV/Pa (nominal pressure sensitivity level is - 26 dB, reference value is 1 V)

Frequency

20 Hz~16 kHz

Frequency Weightings:  

A,C

Time Weightings:

F(Fast) and S(Slow)

Measuring Range

A:30-130dB,C:40-130dB

Threshold Setting Range

30 dB-130 dB, sound level exceeding the threshold, give the sign of exceeding threshold, and output high level.

Automatic calibration range

±4.5dB (reference value is 50mV/Pa)

Screen

128 *64 dot matrix liquid crystal display (LCD), with resolution of 0.1dB, has signs of overload, under-range, low battery voltage alarm, over-threshold alarm and so on.

Analog output

Output jack is 3.5 mm dual-channel headphone jack, minimum load impedance is 10kΩ

---DC logarithmic voltage: The output voltage is logarithmic to the measured sound pressure, and the output voltage per unit sound pressure is 15 mV/dB.
