上图是2400的遥感测量图，是标准的电流电压。而相对的2614B的遥感测量很奇怪

可以看到sense在原本的output外。但是在描述中，应该也在中间才对。

When sourcing voltage with remote sense, the instrument relies on the voltage detected with the
sense lines to provide the proper closed-loop control of its output voltage and to properly limit the
voltage across the device-under-test. If a sense line becomes disconnected from its corresponding
force line, an erroneous voltage is sensed. The output voltage may be adjusted to a level that is
radically different than the programmed voltage level (possibly to hazardous levels, depending on the
model). In addition, the voltage across the device may exceed the programmed source limit voltage,
possibly causing damage to the device or test fixture.

经过测试确实在外侧，但是过于奇怪，写这一篇文章作为记录。
