Instrument card scheme for remote sense
Use remote sense to eliminate the effects of measurement pathway resistance. The following figure
illustrates the use of remote sense in an instrument card configuration. Note that remote sense
requires twice as many measurement pathways. The FORCE pathways (in red) are the
current-carrying pathways, and the SENSE pathways (in blue) are the measurement pathways.
