Leads resistance eliminating method for two-wire resistance measurement:
1. Connect one end of test lead to multimeter, and short together with probe end.
2. Press the softkey of Relative (
) to make zero, and every resistance measurement will
reduce current lead resistance measurement value.
3. Connect test probe end to test circuit, and measure resistance value.
