一般規格
顯示 (Display)
- 52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits.
功能 (Function)
- dB (A & C frequency weighting), Time weighting(Fast, Slow), Hold, Memory ( max. & min. ), Peak hold, AC & RS232 output.
測量範圍 (Measurement Range)
- 30 to 130 dB
解析度 (Resolution)
- 0.1 dB.
精確度 (Accuracy) (23± 5 ℃)
- Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB ( 31.5 Hz to 8 kHz), 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 K Hz ± 1.4 dB
- 2 K Hz ± 2.6 dB ; 4 K Hz ± 3.6 dB ; 8 K Hz ± 5.6 dB
加權網路 (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.
測量頻率 (Measurement Frequency)
- 31.5 Hz to 8,000 Hz.
校正器 (Calibrator)
- B & K (Bruel & kjaer), multi-fuction acoustic calibrator, model : 4226.
麥克風 (Microphone type)
- Electric condenser microphone.
麥克風尺寸 (Size of microphone)
- 1/2 inch standard size.
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.
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.
- * The "Fast" & "Slow" response range are designed to meet IEC 61672 class 2 requirement.
輸出訊號 (Output Signal)
- * AC output - AC 0.5 Vrms corresponding to each range step. Output impedance - 600 ohm.
* RS232 output.
輸出端子 (Output terminal)
- Terminal 1 : RS232 computer interface terminal.
Terminal 2 : AC output terminal.
* Terminal socket size : 3.5 mm dia. phone socket.
校正 VR (Calibration VR)
- Build in external calibration VR, easy to calibrate on 94 dB level by screw driver.
操作溫度 (Operating Temp. )
- 0 to 50 ℃. ( 32℉ to 122℉ ).
操作溼度 (Operating Humidity)
- Less than 80% R.H.
電源供應 (Power Supply)
- 006P DC 9V battery (heavy duty type)
電源損耗 (Power Consumption)
- Approx. DC 6 mA.
重量 (Weight)
- 405 g/0.89 LB ( including probe ).
