Circuit

Custom one-chip of microprocessor LSI circuit.

Display

LCD size : 50 mm x 30 mm

LCD with green backlight ( ON/OFF ).

Measurement Type

SPL : Sound pressure level Dose:test noise exposure

Measurement Range

SPL:Auto 30 - 130 dB.

Dose:70~130dB

Resolution

0.1 dB.

Function

dB ( A & C frequency weighting ), Time weighting ( Fast, Slow ), Data hold

Record ( Max., Min. ).

Accuracy (23 ± 5 ?)

Characteristics of " A " frequency weighting network meet IEC 61672 class 2.

Under 94 dB input signal, the accuracy are :

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 K    Hz

± 1.4 dB

2 K    Hz

± 2.6 dB

4 K    Hz

± 3.6 dB

8 K   Hz

± 5.6 dB

Remark :

The above spec. are tested under the environment RF Field Strength less than 3 V/M & frequency less than 30 MHz only.

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.

 

Time weighting

(FAST & SLOW)

Fast - t = 125 ms

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

Slow - t = 1 s

"Slow" range is easy to get the average values of vibration sound level.

Data hold

To freeze the measurement value.

Function selector SPL  DOSE

Auto  range:30~130dB.

Threshold Level (Thr):70~90dB in 1dB steps. Criterion  Level(Crit):80?84?85?90dB. Exchange Rat :3, 4, 5 or 6 dB

Frequency

31.5 to 8,000 Hz.

Microphone type

Electric condenser microphone.

Microphone size

Out size, 12.7 mm DIA. ( 1/2 inch).

Calibration VR

Build in external calibration VR, easy to calibrate on 94 dB level by screw driver.

* Calibrated via external SOUND CALIBRATOR ( SC-942, optional ).

Calibrator

B & K (Bruel & kjaer), MULTIFUNCTION ACOUSTIC CALIBRATOR Type 4226.

Datalogger Sampling Time Setting range

Auto

1 second to 3600 seconds

@ Sampling time can set to 1 second, but memory data may loss.

Manual

Push the data logger button once will save data one time.

@ Set the sampling time to 0 second.

Memory device

internal memory device :

EEPROM can be record 16,000 items.

external memory device ( AC Adapter only ) : SD memory card. 1 GB to 16 GB.

Power off

Auto shut off saves battery life or manual off by push button.

Operating Temperature

0 to 50 °C.

Operating Humidity

Less than 85% R.H.

Power Supply

Alkaline or heavy duty DC 1.5 V battery ( UM4, AAA ) x 6 PCs, or equivalent.

DC 9V adapter input. ( AC/DC power adapter is optional ).

Power Current
