在评估最大电压或最大电流水平时，要想达到规定的寿命，则必须考虑继电器的功率额定值。
When evaluating either maximum voltage or maximum current levels, the power rating of the relay must also be considered if the specified life is to be attained.
开关卡能够可靠承受的最高电压即为最大电压指标，它主要是由继电器的技术指标决定的。
The highest voltage a switch card can withstand reliably is the maximum volt age specification, which is determined primarily by the relay specification.
如果负载电阻被直接连接到伏特计的输入端子，通过继电器触点的电流会产生电压降，测得的电池电压将存在误差。
If the load resistor was connected directly across the voltmeter input terminals, the current through the relay contacts would cause a voltage drop and the measured cell voltage would be in error.
