To provide the best measurement accuracy, use the four-wire (Kelvin) measurement method for this
test. This method eliminates the effects of lead resistance on the measurement accuracy. It is the
preferred method when measuring low resistances.
To use the 4-wire connection method:
•
Connect one set of test leads to the FORCE LO and FORCE HI terminals; this setup forces a
current through the device under test.
•
Connect the other set of test leads to the SENSE HI and SENSE LO terminals, which measure
the voltage drop across the device under test (DUT).
