Ampetronic FSM Hearing Loop Field Strength Meter

Name: Ampetronic FSM Hearing Loop Field Strength Meter
Brand: Ampetronic

The Ampetronic FSM is a handheld magnetic field strength meter for setting up and commissioning hearing loop systems to IEC 60118-4 (BS EN 60118-4). It measures field strength, A-weighted background noise and frequency response at 100 Hz, 1 kHz and 5 kHz, and has a headphone output for listening to the loop. It works on any manufacturer's loop and is used by installers for commissioning, site surveys and maintenance visits. 400 mA/m0 dB reference3Measurement modes2x AABatteries included5 yearsWarranty FeaturesThree calibrated modes: field strength, A-weighted background noise and frequency responseFrequency response checks at 100 Hz, 1 kHz and 5 kHz, for assessing metal lossTrue RMS detection calibrated to 400 mA/m = 0 dB, 1 dB resolutionColour-coded LED bar graph, green for -3 to +3 dBHeadphone output with volume control for listening to the loopChecks coverage and overspillSupplied with soft case, batteries and commissioning guide5 year Ampetronic warranty SpecificationsReference level400 mA/m (field strength mode)Frequency response50 Hz to 8 kHz (±0.25 dB); 30 Hz to 10 kHz (-3 dB)Gain stabilityBetter than 0.5 dBCoil orientationVertical with unit held uprightHeadphone output3.5 mm stereo jack, 16 ohm minimumPower2x AA alkaline (supplied)Battery lifeUp to 100 hoursDimensions84 x 27 x 140 mmWeight150 g without batteriesOperating range-10 to 45°C, 10 to 85% relative humidityShow more
