EASUREMENT CONFIGURATIONS
The instrument's normal operating mode as SLM assumes operating with the preamplifier and
microphone attached to the instrument and without a windscreen. Optionally the instrument can be
operated with the windscreen attached to the microphone or with the preamplifier and microphone fitted
in the outdoor microphone kit and connected with the instrument by the extension cable (see Appendix C
for specification).
In the case of significant dif
ferences between the instrument’s temperature and the ambient temperature
at the measuring point, long enough acclimatization of the instrument is recommended so that its
temperature is as close to the ambient temperature as possible.
In the case of measurements in the presence of wind, it is necessary to use a windscreen. The
windscreen should be simply installed over the microphone with the preamplifier without any significant
force.
To have measurements in accordance with the IEC 61672-1:2013 standard it is necessary to set the
appropriate compensation in the
Compensation Filter screen (see Chapter 4.7 ).
When measuring in the diffusion field (in small spaces) it is recommended to switch on the filter for the
diffusion field.
Chapter 16.3 presents the way the microphone should be attached to the preamplifier and the
preamplifier to the instrument.
