Safety instructions
Dealing with electromagnetic radiation
– The measuring device complies with electromagnetic compatibility regulations and limits in accordance
with the EMC Directive 2014/30/EU which is covered by the Radio Equipment Directive 2014/53/EU.
– Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people
with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or
be subject to hazards or interference.
– The measuring accuracy may be affected when working close to high voltages or high electromagnetic
alternating fields.
1
Insert battery
Open the battery
compartment and insert
batteries (6 x type AAA)
according to the symbols.
Be sure to pay attention
to polarity.
3
Setting date/time (setup)
The current data and time should be set before using the
device for the first time to ensure stored measured values
are assigned for subsequent evaluation. Press and hold
the "MAX" button while switching on. You can change
the value with the "LEVEL" buttons and move to the next
value with the "MAX" button.
Date format: Year/month/day. Switch off the device to
store the setting.

Sound pressure level (dB)
This device registers sound in a similar way to the human ear. The
integrated microphone receives the incoming sound waves and
converts them into electrical signals. Human hearing involves specific
auditory curves. The greater the sound pressure, the louder the
sound is perceived to be. The higher the frequency, the higher the
pitch of the sound is perceived to be. To ensure that measurements
are aurally compensated, this measuring device is fitted with filters.
The A-weighting (dB A) replicates the frequency response associated
with human hearing and is used for the majority of industrial noise
and environmental noise measurements.
The C-weighting is used in industrial measurements.
After switching on the device, correspondingly switch over
the dB A/dB C weighting filter by pressing the "A/C" button.
!
Powerful wind noises (> 10m/s) can affect the measured value. In such cases, you should use the
wind deflector supplied with the product.
