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 651 type 2, calibrating input signal on 94 dB(31.5 Hz to 8

(23 ± 5 ) kHz), then the accuracy of A weighting is specified as following:

31.5 Hz - ± 3 dB, 63 Hz - ± 2 dB, 125 Hz - ± 1.5 dB

250 Hz - ± 1.5 dB, 500 Hz - ± 1.5 dB, 1 kHz - ± 1.5 dB

2 kHz - ± 2 dB, 4 kHz - ± 3 dB, 8 kHz - ± 5 dB

Characteristics of A & C.

Frequency A weighting - The characteristic is simulated as "Human Ear Listing" response. Typical, if making

Weighting Network 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 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.

Out terminal 3.5 phone output terminal is provided for connection with analyzer, level recorder, tape

recorder.

Operating Temp. 0 to 50 ( 32 to 122 ).

Operating Humidity Less than 80% RH

Power Supply 006P DC 9V battery(heavy duty type).
