This may require using a high current switch card for sourcing and a low voltage switch card for measuring.
这就可能需要利用一个大电流开关卡来提供电流，一个小电压开关卡用于测量。
The highest voltage a switch card can withstand reliably is the maximum volt age specification, which is determined primarily by the relay specification.
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。
To prevent damage to the switch card, verify that the product of the maximum current and maximum voltage does not exceed the power rating of the switch card.
为防止损坏开关卡，需验证最大电流和最大电压的乘积没有超过开关卡的功率额定值。
