SigNET AC FPRO Induction Loop Test Meter

The SigNET AC FPRO Induction Loop Test Meter allows for careful testing and calibration of an induction loop system prior to operation. The most efficient way of doing this is to use the FPRO. The current standard EN 60118-4 recommends that the achievable magnetic field strength of an AFILS over a 'covered area' should be 400 mA/m at least at one point. The most effective way of ensuring this requirement is met is to measure the magnetic field strength of a consistent output from an AFILS amplifier using the FPRO.

SigNET AC FPRO Induction Loop Test Meter Features

- Measures magnetic field strength, background noise, frequency response, metal compensation plus voice and music
- A digital LCD; provides a user-friendly interface to simplify testing. Contrast controls and battery life indication are also provided
- Two 'soft' buttons; change their functions to suit the menu options being accessed
- Auto power-off feature; warns the user after 10 minutes of no buttons being pressed, then gives the user 30 seconds to shutdown the device, or postpone the event
- 3.5 mm headphone jack socket; allows audible monitoring using headphones
