2w_4w_ohms.pdfWhat is the difference between 4-wire and 2-wire Ohms measurements? Figure 1 below illustrates the method used in 2-wire Ohms measurement. The test current (I) is forced through the test lead into the Device Under Test (R). The Voltmeter (Vm) measures the voltage developed at the HI and LO terminals. This voltage will be from the IxR drop across the Device Under Test (DUT) as well as from the IxR from the test leads. Measured Resistance = Vm = Rs + (2xRLead ) I Typical Lead Resistance is in the range of 1mohm to 100mohms. This Lead Resistance will be a significant source of error if your DUT is below 10 Ohms. Test Current DMM Hi R Lead Voltage Measured Voltage Acorss Vm
