精確度 (Accuracy) (23± 5 ℃)
- Characteristics of " A " frequenc 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 KHz : ± 1.4 dB
- 2 KHz : ± 2.6 dB
- 4 KHz : ± 3.6 dB
- 8 KHz : + 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.
頻率加權網路 (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.
快慢時間加權 Time weighting (Fast, Slow)
- Fast - t= 125 ms
- Slow - t = 1 s
- * "Fast" range is simulated the human ear response time.
- * "Slow" range is easy to get the avg. values of vibration sound level.
