If you want to measure according to IEC standards (i.e.
free field), simply point the sound level meter towards
the sound source.
If you want to measure according to ANSI standards (i.e.
diffuse field), fit the supplied Random Incidence Corrector
DZ9566 on the microphone. The direction of the sound
level meter is unimportant. If, however, the sound field
is free, measure with the sound level meter at an angle
of between 70 and 80˚ to the sound source.

The sound level meter starts measuring with the selected

Note:
●
When mounting the sound level meter on a tripod, posi-

direction as the sound level meter. This will reduce the
risk of damaging the microphone if the tripod is acciden-
tally knocked over.

See section 1.3 for practical hints and information about
measuring according to standards.
