中文名称： 偏移电流 英文名称：Offset Current 定义：安培计在输入开路时由于有源器件的偏置电流以及流过仪器中绝缘体的漏泄电流产生的小电流。
这种偏移电流的典型来源是绝缘子和电缆。
Typical sources of such offset currents are insulators and cables.
对于切换小电流来说，开关卡的偏移电流指标应该尽可能小。
The offset current specification of the switch card should be as low as possible for switching low current.
为了获得准确的结果，偏移电流技术指标必须小于被切换的信号电流。
To achieve accurate results, the offset current specification must be smaller than the signal current that is being switched.
