Resolution  0.1 dB.

Function

dB ( A & C frequency weighting ),

Time weighting ( Fast, Slow ),

Peak hold, Data hold Record ( Max., Min. ).

Accuracy (23 ± 5 ℃)

Characteristics of "A" frequency weighting network meet IEC 61672 class 1

Under 94 dB input signal, the accuracy are :

31.5 Hz : ± 2.0 dB

63 Hz : ± 1.5 dB

125 Hz : ± 1.5 dB

8 K Hz : + 2.1 dB , -3.1 dB

12.5 KHz : + 3.0 dB, -6.0 dB

16 KHz : + 3.5 dB, -17.0 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.

Data hold  To freeze the measurement value.

Peak hold  To keep the peak ( max. ) measurement value.

Time weighting (Fast & Slow)

Fast - t= 200 ms

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

Slow - t = 500 ms

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

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.

Frequency  31.5 to 16 KHz.

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-941, optional ).

Calibrator  B & K (Bruel & kjaer), Multifunction Acoustic Calibrator 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.

@ Manual mode, can also select the 1 to 99 position ( Location ) no.

Advanced setting

* Set clock time ( Year/Month/Date,Hour/Minute/ Second )

* Decimal point of SD card setting

* Auto power OFF management

* Set beep Sound ON/OFF

* Set sampling time

* SD memory card Format

Over Indication  Show " - - - - ".

Data Hold  Freeze the display reading.

Memory Recall  Maximum & Minimum value.

Sampling Time of Display  Approx. 1 second.

Data Output  

RS 232/USB PC computer interface.

* Connect the optional RS232 cable UPCB-02 will get the RS232 plug.

* Connect the optional USB cable USB-01 will get the USB plug.

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