Initial Operation

Make sure that you have sufficient ear protection for loud noise sour-
ces. Risk of hearing damage.
Pay attention to the permitted environmental conditions (technical
data) to avoid faulty measurements.
Switch the appliance on using the On/Off switch (2). Pressing the switch always swit-
ches the appliance on or off.
The measurement begins immediately after switching the appliance on. The measure-
ment, and the unit „dBC", are shown on the display.
In bad light conditions, the display light automatically switches on. The light sensor (3)
controls the display light.
If no button is pressed for 15 minutes, the meter switches off automatically. This saves
the battery. When needed, switch the appliance on again using the On/Off switch.
Making Measurements
Measurement of a noise source has always to be carried out directly.
Ensure that there are no objects or persons between the microphone
and the noise source.
Direct the noise level meter with the microphone (1) directly towards the noise source.
To avoid affecting the sound waves hold the measuring device as far away from your
body as possible or place it on a stand. A stand fastening (6) is on the rear of the ca-
sing. Avoid vibrations or movements.
Increase the distance to the object you want to measure, if the measuring range is ex-
ceeded (OVER).
Use the enclosed wind deflector (8) for wind (>10m/s) so as not to distort
the measurement through wind sounds. The wind deflector does not dis-
tort the measurement results.
MAX/MIN function
For continuous measurements, only the maxima or minima value is shown on the dis-
play. This measurement function makes it easier for you to determine the peak level.
The MAX function is activated by pressing the MAX-MIN button on the side. Pressing
the switch again switches to the MIN operation and vice versa. The respective function
is shown as „MAX" or „MIN" on the display.
In order to deactivate this measuring function hold the MAX-MIN button pressed for ap-
proximately 2 seconds or turn the measuring device off.

Maintenance and Cleaning

The measuring device is absolutely maintenance-free, apart from occasional cleaning.
To clean the device and the display, use a clean, lint-free, antistatic and slightly damp
cleaning cloth.
