10. Measuring the sound level

Exercise caution in loud environments. You may suffer hearing damage. Always use hearing protection in
loud environments! Ensure that there are no objects or people between the measurement microphone (9)
and the sound source.
Sound sources must always be measured directly. Point the sound level meter and microphone directly at
the sound source.
To avoid influencing the sound waves, keep the meter as far away from your body as possible using an outstretched
arm, or attach it to the enclosed tripod. If possible, move away from the measuring point. There is a tripod socket (10)
on the back of the meter.
Avoid vibrating or moving the meter.
