Specification
Display :52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits.
Function :dB (A & C frequency weighting), Time weighting(Fast, Slow), Hold, Memory (max. & min.), Peak hold, AC & RS232 output.
Measurement Range :30 - 130 dB.
Resolution :0.1 dB.
Accuracy (23 ± 5 ℃) :Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB ( 31.5 Hz
to 8 KHz), then the accuracy of frequency weighting is specified as following:
31.5 Hz - ± 3 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
Frequency Weighting Network : 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.
Frequency 31.5 Hz to 8,000 Hz.
Calibrator :B & K (Bruel & kjaer), multi-fuction acoustic calibrator, model : 4226.
Microphone :Electric condenser microphone.
Size of microphone :1/2 inch standard size.
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.
Time Weighting (Fast & Slow) :Fast - t= 200 ms, Slow - t = 500 ms,
* "Fast" range is simulated the human ear response time weighting.
"Slow" range is easy to get the average values of vibration sound level.
* The "Fast" & "Slow" time weighting range are designed to IEC 61672 class 2 requirement.
Output Signal :* AC output - AC 0.5 Vrms corresponding to each range step. Output impedance - 600 ohm.
* RS232 output.
Output terminal :Terminal 1 : RS232 computer interface terminal.
Terminal 2 : AC output terminal.
* Terminal socket size : 3.5 mm dia. phone socket.
Calibration VR :Build in external calibration VR, easy to calibrate on 94 dB level by screw driver.
Operating Temp. :0 to 50 (32 to 122). ℃ ℃℉ ℉
Operating Humidity :Less than 80% RH.
Power Supply :006P DC 9V battery (Alkaline or heavy duty type).
Power Consumption :Approx. DC 6mA
Dimension :Main instrument :205 x 68 x 29 mm (8.07x2.7x1.1 inch).
Sound probe :170.5 x 24.5 x 19 mm (6.7x1.0x0.7 inch).
Weight :405 g/0.89 LB (including probe).
