Weight	1 kg

GENERAL SPECIFICATIONS

Circuit	Custom one-chip of microprocessor LSI circuit.
Display	LCD size : 52 mm x 38 mm LCD with green backlight ( ON/OFF ).
Measurement Range	30 – 130 dB.
Resolution	0.1 dB.
Function	dB ( A & C frequency weighting ), Time weighting ( Fast, Slow ), Peak hold, Data hold Record ( Max., Min. ).
Accuracy (23 ± 5 °C)	Characteristics of ” A ” frequency weighting network meet IEC 61672 class 2. Under 94 dB input signal, the accuracy are : 31.5 Hz 63 Hz 125 Hz 250 Hz 500 Hz 1KHz 2KHz 4KHz 8KHz Remark The above spec. are tested under the environment RF Field Strength less than 3 V/M & frequency less than 30 MHz only. : ±3.5dB ±2.5dB ±2.0dB ±1.9dB ±1.9dB ±1.4dB ±2.6dB ±3.6dB ±5.6dB
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 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-941, optional ).
Calibrator	B & K (Bruel & kjaer), MULTIFUCTION 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.
Memory Card	SD memory card. 1 GB to 16 GB.
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.
AC output	AC 0.5 Vrms corresponding to each range step. * Output impedance : 600 ohm.
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 ( UM3, AA ) x 6 PCs, or equivalent.
	* ADC 9V adapter input. ( AC/DC power adapter is optional ).
Power Current	Normal operation ( w/o SD card save data and LCD Backlight is OFF) : Approx. DC 8.5 mA.
	When SD card save the data but and LCD Backlight is OFF) : Approx. DC 30 mA.
	* AIf LCD backlight on, the power consumption will increase approx. 14 mA.
Weight	489 g/1.08 LB.
Dimension	245 x 68 x 45 mm. ( 9.6 x 2.7x 1.9 inch ).
Accessories Included	* Instruction manual………………….. 1 PC
Optional Accessories	* Sound calibrator ( 94 dB ), SC-941. * Sound calibrator ( 94/114 dB ), SC-942. * Sound wind shield ball, SB-01 * SDCard(1GB) * SDCard(2GB) * USB cable, USB-01. * RS232 cable, UPCB-02. * Data Acquisition software, SW-U801-WIN. * AC to DC 9V adapter. * Soft carrying case, CA-05A. * Hard carrying case, CA-06.
