PROLOOP FSMplus – Measuring device for induction loop systems

 

The PROLOOP FSMplus is a mea­suring device that measures the magnetic field strength of induction loop systems according to IEC 60118-4:2006 and BS 6083, Para. 4. The device delivers reliable RMS values on the output level, response frequency, AGC function (Automatic Gain Control), distortion and background noise in the induction looped tested. In addition, it enables the user to make an acoustic evaluation of the sound using signal reproduction via earphones.
