The method of usage
01) Press the power button, the LCD displays the default range (40~90dB) and the sound level of a spot.
If the “UNDER” or “OVER” symbol appears on the display, it indicates the sound level is less than or more than 40~90dB,. That means the measurement is invalid. you need to set the meter’s range to a correct position.
02) Set range:
Press LEVEL ▲ or ▼, choose the proper range, measure the sound level of the desired spot.
When the “UNDER” symbol appears on the display, it means that the range is high, you need to press
LEVEL▼ to set a lower range until the “UNDER” symbol disappears.
When the “OVER” symbol appears, it means that the range is low, you need to press LEVEL▲ to set a higher range until the “OVER” symbol disappears.
03) Choose weighting mode:
When you measure a general noise sound level, you could choose ‘A’ weighting by pressing the A∕C
04) button. To measure an acoustic sound level , choose “C”.
When you want to get a real-time sound level measurement, choose FAST by pressing the FAST∕SLOW button. To get an average sound level, choose “SLOW”.
05) When you want to get the maximum value of a sound level measurement, you have to press the
“MAX” button.
06) When you want to measure in dark surroundings or at night, you can activate the background light by pressing “LIGHT” button.
