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。
Test and mark the resistance value of the old elements having been replaced (with voltmeter and ammeter) and distribute them in low temperature area.
换下来的元件重新（用压表、电流表）测标其电阻值，配阻用在低温区。
