TECHNICAL SPECIFICATION
TECHNICAL SPECIFICATION | |
Applied Standards: | GB/T3785,Class 1; IEC61672,Class 1 |
| 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 1 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. ---AC Linear Voltage: The output voltage is linearly correlated with the measured sound pressure, and the output voltage corresponding to the upper boundary of the stage range is 2.0V. |
