The connections to the PRT should be short (low resistance) in order to minimise the
effect of lead resistance on the measurement. Alternatively, the connections can use
remote sensing (using the 4-wire measurement capability of the milliK) to eliminate the
effect of lead resistance completely. In this arrangement, the current and voltage sense
connections are kept separate and are only joined close to the PRT:

The top (green) terminal should be connected to the screen of the PRT’s lead (where
present) to minimise electrical noise picked up by the wires.
