Your purchase of this SOUND LEVEL METER with SD CARD DATA RECORDER marks a step forward for you into

the field of precision measurement. Although this METER is a complex and delicate instrument, its durable structure

will allow many years of use if proper operating techniques are developed. Please read the following instructions

carefully and always keep this manual within easy reach.

1. FEATURES

* Main functions are designed to meet IEC 61672 class 2.

* A & C weighting networks comply with standards.

* 0.5" standard microphone head.

* Time weighting (Fast & Slow) dynamic characteristic modes.

* Build External calibration VR.

* Auto range & Manual range selection.

* Available for external calibration adjustment.

* Condenser microphone for high accuracy & long-term stability.

* Memory function to store the Max. & Min. value.

* Hold and Peak Hold functions.

* Real time SD memory card Datalogger, it Built-in Clock and Calendar, real time data recorder, sampling time set

from 1 second to 3600 seconds.

* Manual datalogger is available (set the sampling time to 0 second), during execute the manual datalogger function,

it can set the different position (location) No. (position 1 to position 99).

* Innovation and easy operation, computer is not need to setup extra software, after execute datalogger, just take

away the SD card from the meter and plug in the SD card into the computer, it can download the all the measured

value with the time information (year/month/date/hour/minute/second) to the Excel directly, then user can make the

further data or graphic analysis by themselves.

* SD card capacity: 1 GB to 16 GB.

* LCD with green light backlight, easy reading.

* Can default auto power off or manual power off.

* Data hold, record max. and min. reading.

* Microcomputer circuit, high accuracy.

* Power by UM3/AA (1.5V) x 6 batteries or DC 9V adapter.

* RS-232/USB PC COMPUTER interface.

* Heavy duty & compact housing case.

dB (A & C frequency weighting), Time weighting (Fast, Slow), Peak hold, Data hold, Record (Max.,

Min.).

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

Under 94dB input signal, the accuracy are:

31.5Hz ± 3.5dB

63Hz ± 2.5dB

125Hz ± 2.0dB

250Hz ± 1.9dB

500Hz ± 1.9dB

1kHz ± 1.4dB

2kHz ± 2.6dB

4kHz ± 3.6dB

8kHz ± 5.6dB

Remark: The above spec. are tested under the environment RF Field Strength less than 3 V/M &

frequency less than 30MHz only.

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.

Fast – t= 200ms

* «Fast» range is simulated the human ear (Fast & Slow) response time weighting.

Slow – t = 500ms

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

To freeze the measurement value.

To keep the peak (max.) measurement value

Auto range: 30 to 130dB.

Manual range: 3 range, 30 to 80dB, 50 to 100dB, 80 to 130dB, 50dB on each step, with over &

under range indicating.

31.5 to 8,000Hz.

Electric condenser microphone.

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

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

* Calibrated via external SOUND CALIBRATOR (SC-941, optional).
