使高电压通道远离敏感的小电流通道，并使用良好屏蔽的开关，可将这种误差降至最低。
This can be minimized by locating the high voltage channels away from the sensitive low current channels and by using well-shielded switches.
所以将器件的加热效应降到最低的一种方法是使用尽可能低的电流，而在被测器件上仍然保持希望的电压。
Thus, one way to minimize the effects of device heating is to use the lowest current possible while still maintaining the desired voltage across the device being tested.
最低负载电流是必要的运作无误的两线设备。
The minimum load current is necessary for flawless operation with two-wire devices.
