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 allow you to listen and subjectively assess the signal in the loop.

The unit is designed to be used by holding it in hte same position as the hearing aid will be once the system is operational i.e. hold the unit at head height to take measurements - either seated or standing, depending on the venue.

 

3 calibrated operational modes:

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. 

Field Strength - A broad band measurement to measure field strength delivered by the 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 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.
