Measuring Resistance

2-Wire Measurements

For many applications the simple 2-wire arrangement will be adequate. See Figure 3-5.
However, the value displayed will include the resistance of the connecting leads.
Use a shielded twisted-pair cable, preferably of PTFE insulation, to reduce induced
voltages, induced charge and shunt leakage resistance, particularly where Rx is high.
2-wire resistance measurement is not available when in
to use in the 2
resistance contributions may limit full-scale readout. 2-wire measurements above 1.5
should be made using higher ranges.
