FSM Field strength meter

The FSM Magnetic Field Strength Meter from Ampetronic is a simple solution for measuring, setting up and commissioning an induction loop system to the requirements of IEC60118-4. 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 and with 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. Applications include Simple assessment of any system to IEC60118-4 Three modes of operation for three test types A-Weighted background noise • Broad band mode (50Hz – 8kHz) Frequency response (100Hz, 1kHz, 5kHz) True RMS detection calibrated to 400mA/m = 0dB Wide viewing angle LED display Colour coded LEDs for simple readout Resolution to 1dB Head phone output with volume control Ergonomic, rugged, light weight construction
