2. Measurement functions
(-20dB) measurement range for back-
ground noise
Increases the sensitivity of the de-
vice and is used to detect magnetic
interference fields. This function can
be used to determine the crosstalk of
the loops. Measurement range from
-43 to -12 dB.
(0dB) measurement range for
magnetic field strength
A broadband measurement range
used to check the field strength that
the induction loop emits.
Filter A
Evaluates the values measured on
the basis of the listening curve of the
human ear.
Filter Norm
Evaluates all the values measured in
the same way on the basis of their
physical values.

3. Using the meter
Before you begin with the calibra-
tion, look for a reference point within
your loop (usually in the middle of the
installed loop). Hold the PROLOOP
FSMplus perfectly perpendicular to
the floor. Be sure to also make a note
of the height at which you hold the
device. This depends on the applica-
tion. Typical values are e.g. 1.20 m
(sitting) or 1.70 m (standing).
