Description
描述
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 (range 1999 mV, resolution 1 mV) 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).
單相交流電源線電磁干擾的測量方法。它的插頭插入插座（電源插座），不需要電池。它立即顯示在毫伏總線噪聲（1999 MV，分辨率為1 mV）在10千赫的頻率范圍（10 MHz的頻率范圍，靈敏度?的最大靈敏度）。一個揚聲器播放EMI，聲幅值解調，以確定電磁干擾源（如一個上午或短波電臺與電機與電弧）。
