General

The measurements have to be carried out in compliance with the respective-
ly applicable standards.
For all tests (measurements) follow the safety references as described
Direct the measurement microphone towards the sound emitting source.
To minimise operator influence on the measurements make sure that the
sound level meter is placed at a distance of approx. 50 cm away from the
body or mounted onto a tripod. The operator body acts as a sound reflector
and can lead to an error of measurement of up to ± 6dB.
During the measurement process, ensure that any persons present do not
influence the sound field, i.e. under no circumstance should the persons be
present within the sound field.
