11. DIGITAL SOUND LEVEL METER

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 (23 ± 5 ℃)

Frequency weighting meet IEC 651 type 2, calibrating input signal on 94 dB(31.5 Hz to 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

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

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 & 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.

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 terminals to be 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).

Power Consumption

Approx. DC 6mA.

Dimension

205 x 80 x 35 mm (8.1 x 3.2 x 1.4 inch).

Weight

280 g/0.62 LB (including battery).

Standard Accessories

Instruction Manual ............... 1 PC. Calibration screw driver.........1 PC.
