Description

Ampetronic FSM+SCC Field Strength Meter with Signal Connection Cables

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.

Applications include:

  • Accurate set-up and commissioning
  • System monitoring and maintenance
  • Site surveys
  • Certification to IEC60118-4:2006
  • Assessment of frequency losses due to metal
  • Assessment of loop coverage and overspill
  • Assessment of background noise

Signal Connection Cables:
The cables allow connection from an audio source on a 3.5mm stereo jack socket such as a headphone output commonly found on most portable audio devices and laptops. They are intended to interface to a wide range of typical inputs and provide appropriate attenuation where applicable.

Features

  • 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
  • Soft carry case
  • 5 year warranty

Specifications

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.

  • A-Weighted filter
  • True RMS detection referenced to 400mA/m
  • Scale -42 to -12dB
  • Audio (headphone) output is post filter for monitoring

Field Strength

A broad band measurement to measure field strength delivered by the system.

  • Broad band measurement 50Hz to 8kHz
  • True RMS detection referenced to 400 mA/m
  • Scale -22 to +8dB with 1dB intervals from -3 to +6dB
  • Suitable for use with sine wave, pink noise, or combination signals (provided), or any other real signals

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.

  • Third octave bands at 100Hz, 1kHz and 5kHz
  • True RMS detection
  • Scale resolution to 1dB
  • For use with pink noise only (signal provided)
  • Audio (headphone) output is post filter
