The FSM is a cost effective and simple solution for measuring, setting
up and commissioning an induction loop system to the requirements
of IEC60118-4:2006. The meter is an ergonomically designed hand
held instrument for measuring loop system performance. There are
three calibrated operational modes for the assessment of Background
Noise, Field Strength and Frequency Response as required to ensure
correct function of the loop system. The meter also doubles as a loop
listener, with a headphone output to listen to the signal in the loop.
The meter is supplied in a soft case with an audio CD with the
required test signals, and full operating instructions including a guide
to commissioning. The Ampetronic FSM can be used to monitor,
set up or commission any induction loop system regardless of the
manufacturer or type.

BackgroundNoise
To determine the level of the background magnetic field present in
the intended location for the loop system. Also used to measure
low level signals to assess overspill outside a loop system.

  FrequencyResponse
Third octave filters for measuring performance across the required
frequency spectrum as required by IEC60118-4.
Used to confirm adequate power at high frequencies as required
for good intelligibility. Used to assess frequency dependent loss
due to metal structures, and to optimise frequency compensation.

The FSM allows a complete test of an induction loop system to be performed with a simple six or seven step procedure as
shown in the table below. Using the FSM with the CD of test signals (included), all aspects of an installation can be examined
and adjusted to meet the requirements. A Certificate of Conformity (template included) is provided to record test results from this
procedure, and to certify that the installation meets the requirements of IEC 60118-4:2006.
