Build External calibration VR.
Auto range & Manual range selection.
Available for external calibration adjustment.
Condenser microphone for high accuracy & long-term stability.
Memory function to store the Max. & Min. value.
Hold and Peak Hold functions.
Real time SD memory card Datalogger, it Built-in Clock and Calendar, real time data recorder , sampling time set from 1 second to 3600 seconds.
Manual datalogger is available ( set the sampling time to 0 ), during execute the manual datalogger function, it can set the different position ( location ) No. ( position 1 to position 99 ).
Innovation and easy operation, computer is not need to setup extra software, after execute datalogger, just take away the SD card from the meter and plug in the SD card into the computer, it can down load the all the measured value with the time information ( year/month/date/ hour/minute/second ) to the Excel directly, then user can make the further data or graphic analysis by themselves.

顯示 (Display)
- Dual function meter's display,
- LCD with green backlight ( ON/OFF ).
測量範圍 (Measurement Range)
- 30 to 130 dB.
解析度 (Resolution)
- 0.1 dB.
功能 (Function)
- dB ( A & C frequency weighting ), Time weighting ( Fast, Slow ), 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 : ± 2.0 dB, 63 Hz : ± 1.5 dB, 125 Hz : ± 1.5 dB,
250 Hz : ± 1.4 dB, 500 Hz : ± 1.4 dB, 1 KHz : ± 1.1 dB,
2 KHz : ± 1.6 dB, 4 KHz : ± 1.6 dB, 8 KHz : + 2.1 dB to -3.1 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.
峰值鎖定 (Peak hold)
- To keep the peak ( max. ) measurement value.
快慢時間加權 Time weighting (Fast, Slow)
- Fast - t= 200 ms, Slow - t = 500 ms,
- * "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 : 3 range, 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step, with over & under range indicating.
