Remote sensing
Remote sensing is used to counteract the effect of wire resistance. For example, if you connect an
electronic load to the DC source, the voltage at the electronic load's terminals will not be the same as
the voltage at the DC source's terminals because of the wire resistance. Using remote sensing, you can
sense the voltage at the electronic load's terminals, effectively cancelling the voltage drop caused by
the wire resistance. When the remote sensing is applied, the power received by the instrument includes
the compensated power for the power dissipated by wire resistance and instrument resistance.
