mean value voltmeter 均值电压表
The offset voltage will cause an error in the applied stimulus to a device under test or the value measured by the voltmeter.
偏移电压会导致施加到被测装置的激励发生误差，或者使伏特计的测量值发生误差。
Operation can be conducted after the indicating value of direct current voltmeter of the panel is zero.
待面板的直流电压表的指示值为0时方可进行操作。
