| Display | 52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits. |
| Measurement Range | 30 - 130 dB. |
| Resolution | 0.1 dB. |
| Function | dB (A & C frequency weighting), Time weighting(Fast, Slow), Hold, Memory ( max. & min. ), Peak hold, AC & RS232 output. |
| Accuracy | Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB(31.5 Hz to 8 kHz), then the accuracy of frequency weighting is specified as following: 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 kHz - ± 1.4 dB 2 kHz - ± 2.6 dB, 4 kHz - ± 3.6 dB, 8 kHz - ± 5.6 dB |
| 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 | / |
| Peak hold | / |
| Time weighting | Fast - t= 200 ms, Slow - t = 500 ms, * "Fast" range is simulated the human ear response time weighting. Slow" range is easy to get the average values of vibration sound level. * The "Fast" & "Slow" time weighting range are designed to IEC 61672 class 2 requirement. |
| Range selector | Auto range : 30 to 130 dB. Manual range : 3 range, 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step, with over & under range indicating. |
