| SPECIFICATIONS | |
| Circuit | / |
| Display | 18mm (0.7") LCD (Liquid Crystal Display), 3 1/2 digits. |
| Measurement Range | 3 ranges, 30 to 130 dB, input signal only. |
| Resolution | 0.1 dB. |
| Function | dB (A & C frequency weighting), Time weighting(Fast, Slow), Max. hold, AC & DC output. |
| Accuracy | Frequency weighting meet IEC 61672-1-2013 class 2, calibrating input signal on 94 dB(31.5 Hz to 8 (23 ± 5 ℃) kHz), then the accuracy of frequency weighting is specified as following: 31.5 Hz -reading ± 3.0 dB, 63 Hz -reading ± 2.0 dB, 125 Hz -reading ± 1.5 dB 250 Hz -reading ± 1.5 dB, 500 Hz -reading ± 1.5 dB, 1 kHz -reading ± 1.0 dB 2 kHz -reading ± 2.0 dB, 4 kHz -reading ± 3.0 dB, 8 kHz -reading ± 5.0 dB |
| Frequency Weighting Network | Characteristics of A & C. A weighting - The characteristic is simulated as "Human Ear Listening" 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 | / |
| Peak hold | / |
| Time weighting | Fast - t= 125 ms, Slow - t = 1 sec., * "Fast" range is simulated the human ear response time weighting. "Slow" range is easy to get the average values of vibration sound level. |
