| Function | dB ( A & C frequency weighting ); Time weighting ( Fast, Slow ); Peak hold, Data hold.; Record ( Max., Min. ). |
| Accuracy | Characteristics of " A " frequency weighting network meet IEC 61672-1-2013 class 1; Under 94 dB input signal, the accuracy are: 31.5Hz reading± 1.5 dB; 63Hz reading± 1.0 dB; 125Hz reading± 1.0 dB; 250Hz reading± 1.0 dB; 500Hz reading± 1.0 dB; 1KHz reading± 0.7 dB; 2KHz reading± 1.0 dB; 4KHz reading± 1.0 dB; 8KHz reading+ 1.5 dB -2.5dB; 12.5KHz reading+ 2.0 dB -5.0dB; 16KHz reading+ 2.5 dB -16.0dB; Remark : The above spec. are tested under the; environment RF Field Strength less |
| Accuracy (cont.) | 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 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 | Freeze the display reading. |
| Peak hold | To keep the peak ( max. ) measurement value. |
| Time weighting | Fast - t= 125 ms; * "Fast" range is simulated the human ear response time weighting.; Slow - t = 1 Sec.; * "Slow" range is easy to get the average values of vibration sound level. |
| 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. |
