Operation
1. Power the meter by pressing the power button. The meter will begin displaying sound level
readings. If the LCD does not switch on, check the 9V battery located in the rear battery
compartment.
2. Hold the meter facing the microphone toward the source of the sound to be measured. For tripod
use, the meter includes a tripod mount on the rear side of its housing.
3. View the measurement on the meter’s LCD. An indication of
OVER
means that the measurement
exceeds 130dB.
4. The meter automatically switches off after 15 minutes of inactivity to conserve battery energy.
Press the power button to switch the instrument on again.
‘A’ Frequency Weighting
With ‘A’ weighting, the frequency response of the meter is similar to the response of the human ear.
‘A’ weighting is commonly used for environmental or hearing conservation programs such as OSHA
regulatory testing and noise ordinance law enforcement.
Fast Response Time
The meter has a fast response time of 125 milliseconds (ms) in order to capture noise peaks and
noises that occur very quickly.
Over Range Alarm (OVER)
If the measurement exceeds 130 dB, the display indicates OVER. To avoid damage to the meter,
do not continue to use the meter in an environment where the sound measured exceeds 130dB.
MAX-MIN HOLD
In this mode, the meter only updates the LCD reading when a higher reading (MAX mode) or lower
reading (MIN mode) is detected. Select MAX HOLD by momentarily pressing the MAX-MIN button.
The meter displays the MAX icon when in the MAX HOLD mode. Press the MAX-MIN button again
to enter the MIN mode (the MIN icon will display). Press and hold the MAX-MIN button to exit this
mode (the MAX-MIN indicators will switch off).
Backlit LCD Display
The LCD is equipped with backlighting for easier viewing, especially in dimly lit areas. The backlight
automatically switches on and off based on ambient light conditions. The backlight sensor located
just above the LCD display and just below the power button senses ambient light conditions.
Battery Replacement
When the low battery icon
BAT
appears on the LCD replace the 9V battery as soon as possible.
The battery compartment cover is located on the rear of the meter. Slide the battery compartment
cover off, change the battery, and replace the compartment cover.
