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 ½ 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).
单相交流电源线电磁干扰的测量方法。它的插头插入插座（电源插座），不需要电池。它立即显示在毫伏总线噪声（1999 MV，分辨率为1 mV）在10千赫的频率范围（10 MHz的频率范围，灵敏度½的最大灵敏度）。一个扬声器播放EMI，声幅值解调，以确定电磁干扰源（如一个上午或短波电台与电机与电弧）。
