4-Wire Resistance Measurement

The Meter incorporates two methods of making a four-wire resistance measurement. The
traditional method is to use four meter leads to connect the Meter to the resistance to be
measured. The optional 2X4 Wire test leads simplifies the four-wire measurement so you
only have to plug in two test leads to the Input HI and LO connectors of the meter.
To perform a 4-wire resistance measurement using four test leads:
