nanovolt

基本解释

A switching matrix using a Model 7168 Nanovolt Card and a Model 7156 General Purpose Card can be constructed to switch the voltmeter and current source among the four sample terminals.
由7168型纳伏卡和7156型通用卡组成的开关矩阵在四个样品端子上切换电压表和电流源。
Nanovoltmeters and nanovolt preamplifiers will rarely indicate zero when no voltage is applied to the input, since there are unavoidable voltage offsets present in the input of the instrument.
当输入端没有施加电压时，纳伏表和纳伏前置放大器很少会指示零读数。这是因为在仪器的输入端不可避免地存在着电压偏置。
