Operation
Measurement Considerations
1. Wind blowing across the microphone increases the noise measurement. Use the supplied
windscreen to cover the microphone when applicable.
2. Calibrate the instrument before each use if possible. Especially if the meter has not been used
for a long period of time.
3. Do not store or operate the instrument in areas of high temperature or humidity.
4. Keep meter and microphone dry.
5. Avoid severe vibration. Protect the meter from impact. Do not drop it. Transport the meter in
the supplied case.
6. Remove the battery when the meter is to be stored for long periods of time.
Basic Operation
1. Turn the meter ON by pressing and holding the button for 1.5 seconds.
2. The meter defaults to AUTO RANGE, ‘A’ Frequency Weighting, and ‘FAST’ Time Response.
3. Select ‘A’ or ‘C” frequency weighting in the SETUP Mode.
4. Select ‘Fast’ or ‘Slow’ response time by pressing and holding the FUNCTION button. Release
the button when the desired setting is displayed. Note that the PEAK HOLD mode of operation
is also accessed in this way.
5. Hold the meter in hand or use the tripod mount to affix the meter in the desired location.
6. To select the range, press and hold the RANGE button until the desired range is shown
(AUTO, 30 to 80, 50 to 100, or 80 to 130db). Use a range that puts the sound level reading in
the center of the range. If dashes appear on the display select a new range if possible. Note
that the overall range of the instrument is 30 to 130 db.
7. The sound level reading is shown in large digits at the center of the LCD.
