Operating Instructions
Power ON/OFF
1. Turn the meter on by pressing the POWER button. To turn the meter
off, press and hold the POWER button for 2 seconds.
Note:
or an optional AC adapter (sold separately).
Basic Operation
1. At start up, the meter's default settings are "Auto Range", "A
Frequency Weighting" and "Fast Time Weighting".

2. Press the Fast/Slow button to select the desired Response Time. If
the sound source consists of short bursts, set the response to FAST
(125ms). To measure average sound level, select SLOW (1 second).
3. Press the A/C button to select the Frequency weighting. Select
"A" Weighting for a general noise sound level, or "C" Weighting for
measuring high level noise. "C" Weighting is a standard weighting of the
audible frequencies commonly used for the measurement of Peak Sound
Pressure Level. If the "C" Weighted level is much higher than the "A"
Weighted level, then there will be a large amount of low-frequency noise.
4. Press the RANGE button to scroll through the four dB range types.
There are three manual dB ranges to select from and auto range. The
manual ranges are described as follows:
Range 1: 30 to 80dB range
Range 2: 50 to 100dB range
Range 3: 80 to 130dB range

or position it on a tripod for long-term monitoring. Point the
microphone in the direction of the noise to take a measurement.
Note: Direct contact with strong winds or blowing air on the microphone
may cause measurement errors. These effects can be reduced by using
the included windshield ball.
Data Hold
1. While taking a measurement, press the HOLD button to freeze the
current readings on the display.
3. Press the HOLD button again to resume normal operation.
Note:POWER
button are disabled.
Peak Hold
1. While taking a measurement, press the LOGGER button to capture
and freeze a noise peak.
2. While in this mode a PEAK symbol will appear and the displayed
reading will only change when a higher sound peak is registered.
3. Press the LOGGER button again to resume normal operation.
Recording Maximum and Minimum Readings
1. Press the REC button to enter recording mode as indicated by
and minimum readings.
2. While in recording mode:
A) Press the REC
B) Press the REC button again and the minimum value will appear
on the display as indicated by "REC MIN".
hold the REC button for two seconds.
Note: When in recording mode the POWER button is disabled and the
meter cannot be turned off.
