(4) Hold the instrument comfortably in your hand or fix on tripod and point the microphone at the

suspected noise source. The sound pressure level will be displayed.

(5) When MAX (maximum hold) mode is chosen. The instrument captures and holds the maximum

noise level for a long period using any of the time weightings and ranges.

(6) When HOLD (data hold) mode is chosen.The hold function freezes the reading in the display.

Press the HOLD button momentarily to activate or to exit the HOLD function

(7) Turn OFF the instrument and remove battery when not in use.

(1) Make the following function switch

settings.

Display: dB, A, Hi or Lo, F

Function: A-Weighting

Response Time: FAST

Level range: 30 to 100dB(Lo) or 60 to

130dB(Hi)

Measurement mode: MAX Hold and

Data Hold Mode function disable.

(2) Insert the microphone housing

carefully into the insertion hole of the

calibrator.

(3) Open battery cover and remove the

battery to adjust the CAL94dB

potentiometer of the unit. The level

display will indicate the desired level.

Our products are all well calibrated

before shipment.

Recommended Recalibration cycle:1

year.

Calibration Procedures

DSM1_manual_book 1/21/32, 10:55 PM6-7

Battery Replacement

Battery Loading

Remove the battery cover on the back to install one 9V Battery.

Battery Replacement

When the battery voltage drops below the operating voltage, the “BAT” icon appears on the LCD

display. If it appears, the battery should be replaced with a new one.

Operating Precautions

(A) Wind blowing across the microphone will bring additional extraneous noise.

When using the instrument in the presence of wind, make sure to mount the windscreen.

(B) Calibrate the instrument before operation if the instrument was not in use for a long time.

(D) Keep microphone dry and avoid severe vibration.

(E) Please remove the battery when not in use.

Measurement

(1) Install a fresh 9-volt battery in the battery compartment.

(2) Turn on power and select the desired response time and weighting. If the sound source consists

of short bursts or you are only catching sound peaks, set the response to FAST. To measure

average sound, use the slow setting.

Select A-weighting for general noise sound level and C-weighting for measuring sound level of

acoustic material.

(3) Select desired Level Range

(1) WINDSCREEN

If you operate at wind speed over 10m/sec, please put protective accessories in front of the

microphone.

(2) DISPLAY LCD

LCD readout for all information

(3) POWER ON/OFF BUTTON

Turn the meter power ON/OFF

(4) BACKLIGHT BUTTON

Turn the meter backlight ON/OFF

(5) A-WEIGHTING / C-WEIGHTING SELECT BUTTON

A — Weighting: For general sound level measurements.

C — Weighting: For checking the low-frequency content of noise.

(NOTE: if the C-Weighting level is much higher than the A-Weighting level, then there is a large

amount of low-frequency noise)

(6) TIME WEIGHTING SELECT BUTTON

F — (Fast Response): For normal measurements (fast varying noise)

S — (Slow Response): For checking average level of fluctuating noise

(7) LEVEL RANGE SELECT BUTTON

Lo — 30~100dB; Hi — 60~130dB

When “OVER” is indicated, the ranges switch to another range of measurement.

(8) MAX / DATA HOLD BUTTON

MAX — Hold position is used to measure the maximum level of sounds. The maximum measured

level is up dated continuously. Pressing the button once again will release the hold and allow a

further measurement.

Data Hold — Press and hold the button for over 2 second to turn on or off data hold function.

The hold function freezes the reading in the display.
