Circuit | Custom one-chip of microprocessor LSI circuit. |
Display | LCD size : 52 mm x 38 mm LCD with green backlight ( ON/OFF ). |
Measurement Range | 30 - 130 dB. |
Resolution | 0.1 dB. |
Function | dB ( A & C frequency weighting ), Time weighting ( Fast, Slow ), Peak hold, Data hold Record ( Max., Min. ). |
Accuracy (23 ± 5 ℃) | Characteristics of " A " frequency weighting network meet IEC 61672 class 2. Under 94 dB input signal, the accuracy are : 31.5 Hz ± 3.5 dB 63 Hz ± 2.5 dB 125 Hz ± 2.0 dB 250 Hz ± 1.9 dB 500 Hz ± 1.9 dB 1 K Hz ± 1.4 dB 2 K Hz ± 2.6 dB 4 K Hz ± 3.6 dB 8 K Hz ± 5.6 dB 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. | |||||||
