The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts peak to peak (range 1999.9 mVp-p, resolution 0.1 mVp-p) in the frequency range 10 KHz – 10 MHz (the frequency limits at which sensitivity is ? of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).
