The PROLOOP FSMplus is a ring loop amplifier with a field strength meter that measures the magnetic field strengths of ring grinding systems. The device provides binding RMS values via output level, response frequency, AGC (Automatic Gain Control) function, distortion, and background noise of the respective loop.
- Allows acoustic sound evaluation by means of signal reproduction via earphones.
- True RMS: 125 ms average time.
- Crest Factor: 3.
- A filter.
- Measuring range: +6 dB to - 40 dB (0 dB = 400 mA / m).
- Headphone output with volume control.
- Meets IEC 60118-4: 006 and BS for measuring instruments for ring loop testing.
- Power supply: 2x 1.5V AA batteries, long battery life.
- Battery status control via LED.
- Field strength via LED scale (about 1dB resolution).
