zero voltmeter

基本解释

Connect a warmed-up sensitive voltmeter or nanovoltmeter to a low volt age calibrator and output zero volts.
将一个已预热的灵敏伏特计或纳伏表连接到一个低压校准器，并输出零伏。
Ideally, when a voltmeter is connected to a relatively low impedance circuit in which no voltages are present, it should read zero.
在理想的情况下，当把电压表连接到一个没有电压的、阻抗比较低的电路时，电压表的读数应当为零。
This system consists of DC standard voltage source, zero magnetic flow current mutual inductor , transconductance amplifier, current divider, standard resistance and digital voltmeter.
该系统由直流标准电压源、跨导放大器、零磁通电流互感器、分流器、标准电阻和数字电压表组成；
