Information about the device
Device description
The digital sound level meter was specifically designed to
perform noise measurements and quality inspections in various
areas and different locations. The measurements can be carried
out e.g. at your workplace, at the office, in factories, schools, at
home or on busy roads. This permits the introduction of
preventative measures and helps to guard against noise-
induced diseases.
• The device meets the requirements of the standard for
digital sound level meters DINEN61672-1.
• display of maximum and minimum values
• indication when exceeding the measuring range
• indication when falling below the measuring range
• dBA and dBC display
• Measuring range selection

Switching the device and performing measurements
Info
Please note that moving from a cold area to a warm
area can lead to condensation forming on the device's
circuit board. This physical and unavoidable effect can
falsify the measurement. In this case, the display
shows either no measured values or they are incorrect.
Wait a few minutes until the device has become
adjusted to the changed conditions before carrying out
a measurement.
Info
Please note that the measurement of a sound source
always has to be carried out directly. There must be no
objects or persons located in between the microphone
and the sound source, unless their influence on the
sound intensity is to be measured on purpose as well.
1. Press and hold the On/offbutton(6) for approx. 2s.
ðThe display(2) is switched on and the device is ready
for operation.
ðThe current measured value is displayed in the
measurement value display(25).
2. Point the device at the sound source to be measured.
ðWait for a moment to achieve a stable measured value.
Setting the measuring range
The device has different measuring ranges which can be
selected as needed or according to the expected sound level. If
the expected sound level range is a known factor, one should
always select the corresponding measuring range whenever
possible, since this permits an optimum resolution of the
scale(13) at all times.
• Lower measuring range: 30 to 80dB
• Medium measuring range: 50 to 100dB
• Upper measuring range: 80 to 130dB
• Auto: 30 to 130dB
Please proceed as follows to set the measuring range:
1. Press the LEVEL(9)button once to switch from the "low"
LEVEL(stage01) to the "medium"LEVEL(stage02).
2. Press the LEVEL(9)button again to switch from the
"medium"LEVEL(stage02) to the
