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

When “OVER” is indicated, the ranges switch to another range for measurement.
8. MAX/HOLD
The hold function freezes the reading in the display. Press the HOLD button momentarily to activate or to exit the
HOLD function.
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.
(Maximum Hold: Decay < 15 digits/3min).

Calibration
ZSM 130
Using a standard Acoustic Calibrator (94dB, 1kHz Sine wave)
1. Make the following buttons and function switch settings.
Display: dB, A, Hi or Lo, F
Function: A-Weighting
Response Time: FAST
Level range: 35 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 СAL94dB 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.

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, appears. If it appears, battery should
be replaced with new one.
Precautions
Wind blowing across the microphone would bring additional extraneous noise.Once using the instrument in the
1.
presence of wind, it is a must to mount the windscreen to not pick up undesirable signals.
Calibrate the instrument before operation if the instrument was not in use for a long time or operated at bad envi-
2.
ronment.
Do not store or operate the instrument at high temperature and high humidity environment.
3.
Keep microphone dry and avoid severe vibration.
4.
Please take the battery and keep the instrument in low humidity environment. When not in use.
5.
Measurement
Open battery cover and install a 9-volt battery in the battery compartment.
1.
Turn on power and select the desired response Time and weighting. If the sound source consists of short bursts
2.
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.
