The Field Strength Meter helps assist in measuring, adjusting and commissioning a hearing loop system by measuring magnetic loop signals and testing for Electromagnetic Background Noise. Lightweight, ergonomic meter has two calibrated measuring functions and two types of filters for removing background noise and adjusting magnetic field intensity. Filter measuring functions by the basis of the listening curve of human ears (A) or by the basis of their physical values (Norm). Measure the loop signal function for background noise (-20dB) or field strength (– 0dB) with the selection button. Provided headphone jack allows the user to listen to the loop output while evaluating the loop field strength.
