Specification
- Performance level: GB/T3785 and IEC61672 level 1.
- Measured evaluation quantity: 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: HY207 type 1 engineering measurement microphone, nominal diameter 12.7 mm, free-field frequency response.
- The nominal sound pressure sensitivity is 50 mV/Pa (the nominal sound pressure sensitivity level is -26 dB, and the reference value is 1 V).
- Frequency range: 10 Hz~20 kHz.
- Frequency weighting: A weighting, C weighting.
- Time weighting: F (fast response), S (slow response).
- Measuring range: A sound level: 30 dB ~ 130 dB; C sound level: 40 dB ~ 130 dB.
- Threshold setting range: 30dB ~ 130dB, when the sound level exceeds the threshold, a sign of exceeding the threshold will be given, and a high level will be output.
- Automatic calibration range: ±4.5dB (reference value is 50mV/Pa).
- Display: 128x64 dot matrix liquid crystal display (LCD), resolution 0.1dB, with signs such as overload, under-range, low battery voltage alarm, and over-threshold alarm.
- Analog output: The output jack is a 3.5 mm dual-channel headphone jack with a minimum load impedance of 10kΩ.
