Peak hold
Data hold Record ( Max., Min. )
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.
資料鎖定 (Data hold)
Freeze the display reading.
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.
範圍選擇 (Range selector)
Auto range : 30 to 130 dB.
Manual range : 2 range
30 to 80 dB
80 to 130 dB
50 dB on each step, with over & under range indicating.
測量頻率 (Measurement Frequency)
31.5 Hz to 8,000 Hz.
麥克風 (Microphone type)
