③ Power ON/OFF button I

Turn the meter power ON/OFF

④ Backlight Button:

Turn the meter backlight ON/OFF
MAX Hold button MAX
The max. Hold position is used to measure the maximum level of sounds. The maximum
measured level is up dated continuously. Press once again the button, will release the hold and
allow a further measurement.

⑤ A-weighting / C-weighting select button A/C

A: A – Weighting. For general sound level measurements.
C: C – Weighting. For checking the low- frequency content of noise.

S
F

dB

(If the C-Weighted level is much higher than the A-Weighted level, then there is a large amount of
low-frequency noise)

⑥ Time weighting select button F/ S

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/Hi

Lo: 30~100dB; Hi: 60~130Db

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

⑧ MAX/ Hold button MAX/HOLD

The max. Hold position is used to measure the maximum level of sounds. The maxim um measured
level is up dated continuously. Press once again the button, will release the hold and allo w a further
measurement. Data Hold button: 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 d isplay.

⑨ Microphone

1/2 inch Electret Condenser microphone

⑩ Battery Co ver

V. Measurement Preparation

(1) Battery loading
Remove the battery cover on the back and put in one 9V Battery.
(2) Battery Replacement
When the battery voltage drops below the operating voltage, mark “BAT” appears. If it appears,

battery should be replaced with new one.

VI. Operating Precautions

(1) Wind blowing across the microphone would bring additional extraneous noise.

Once using the instrument in the presence of wind, it is a must to mount the windscreen to not pick
up undesirable signals.

(2) To achieve more accurate measurement, use an extension cable to separate the Microphone from

the main body so that the effect of unexpected sound reflection can be eliminated.

(3) Calibrate the instrument before operation if the instrument was not in use for a long time or operated

at bad environment.
(4) Do not store or operate the instrument at high temperature and high humidity environment.
(5) Keep microphone dry and avoid severe vibration.
(6) Please take the battery and keep the instrument in low humidity environment. When not in use.

VII. Measurement

(1) Open battery cover and install a 9-volt battery in the battery compartment.
(2) Turn on power and select the desir ed respons e Time and weighting. If the sound source consists of

short bursts or only catching sound peak, set 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
(4) Hold the instrument comfortably in hand or fix on tripod and point the mic rophone 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 and remove battery when not in use.
