zero voltmeter

基本解釋

Connect a warmed-up sensitive voltmeter or nanovoltmeter to a low volt age calibrator and output zero volts.
將一個已預熱的靈敏伏特計或納伏表連接到一個低壓校準器，并輸出零伏。
Ideally, when a voltmeter is connected to a relatively low impedance circuit in which no voltages are present, it should read zero.
在理想的情況下，當把電壓表連接到一個沒有電壓的、阻抗比較低的電路時，電壓表的讀數(shù)應當為零。
This system consists of DC standard voltage source, zero magnetic flow current mutual inductor , transconductance amplifier, current divider, standard resistance and digital voltmeter.
該系統(tǒng)由直流標準電壓源、跨導放大器、零磁通電流互感器、分流器、標準電阻和數(shù)字電壓表組成；
