Product Description

SPECIFICATIONS
Display 18mm (0.7″) LCD (Liquid Crystal Display), 3 1/2 digits.
Function dB (A & C frequency weighting), Time weighting(Fast, Slow), Max. hold, AC & DC output.
Measurement Range 3 ranges, 30 to 130 dB, input signal only.
Resolution 0.1 dB.
Accuracy Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB(31.5 Hz to 8
(23 ± 5 ℃) kHz), then 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 kHz – ± 1.4 dB
2 kHz – ± 2.6 dB, 4 kHz – ± 3.6 dB, 8 kHz – ± 5.6 dB
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.
Frequency 31.5 Hz to 8,000 Hz.
Calibrator B & K (Bruel & kjaer), multi-fuction acoustic calibrator, model : 4226.
Microphone type Electric condenser microphone.
Size of microphone 1/2 inch standard size.
Range selector 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 – t= 200 ms, Slow – t = 500 ms,
(Fast & Slow) * “Fast” range is simulated the human ear response time weighting.
“Slow” range is easy to get the average values of vibration sound level.
Calibration * Build in external calibration VR, easy to calibrate by external screw driver.
* Internal oscillation system, 1 KHz sine wave generator.
Output Signal AC output – AC 0.5 Vrms corresponding to each range step.
DC output – DC 0.3 to 1.3 VDC, 10 mV per dB.
Out put impedance – 600 ohm.
Output terminal 3.5 mm phone output terminal is provided for connection with analyzer, level recorder, tape
recorder.
