SPECIFICATIONS

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 Frequency weighting meet IEC 61672 type 2, calibrating input signal on 94 dB(31.5 Hz to

(23 5 ) 8 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,

2kHz - ± 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

Weighting Network 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.

Fast - t= 200 ms, Slow - t = 500 ms,

Time Weighting * "Fast" range is simulated the human ear response time weighting.

(Fast & Slow) "Slow" range is easy to get the average values of vibration sound level.

* The "Fast" & "Slow" time weighting range are designed to IEC 651 type 2 requirement.

Output Signal * AC output - AC 0.5 Vrms corresponding to each range step.

Output impedance - 600 ohm.

* RS232 output.

Out terminal Terminal 1 : RS232 computer interface terminal.

Terminal 2 : AC output terminal.

 

 

* Terminal socket size : 3.5 mm dia. phone socket.
