Operation

When taking measurements, always point the measuring microphone (2) exactly
towards the sound source to be measured.
Ensure that there are no persons or objects between the measuring microphone (2)
and the sound 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.
Avoid vibrations or movements.
Use the enclosed wind deflector (1) for wind or strong draughts so as not to distort
the measurement through wind sounds. The wind deflector (1) does not distort the
measurement results.

The automatic switch-off is activated when the device is switched on the next time.
• When switched on, the sound level meter immediately begins to measure the sound level and
displays the measured values in the measurement value display (8).
• Press the button to toggle between maximum measurement value, minimum measu-
rement value and current measurement value. The currently displayed values are indicated
with the MAX/MIN display (5) (nothing displayed >> current measurement value).
• Press the button to "freeze" the displayed value. The current measurement value is
shown continuously, HOLD (6) is shown in the display. Press the
to the normal display.
• Press and hold the button to switch the display light on or off.
• Press the button to toggle the measurement interval. FAST/SLOW (9) in the display
indicates the set measurement interval (FAST = 125 ms, SLOW = 1 s).
The FAST setting is used for quickly changing sound levels. The SLOW setting is
used for continuous, constant sound levels.
• If the measured values are outside of the measurement range, the display (3) shows "UN" or
"OL" ("UN" = measurement values < 30 dB, "OL" = measurement values > 130 dB).
