Using the offset compensation method, Smart removes unexpected DC
voltages within instrument, at the input, or the circuit being measured, which will
add error to resistance measurement. Besides, it also displays the bias voltage or
leakage current (calculated based on bias voltage and corrected resistance value)
on the secondary display. With offset compensation method, the multimeter takes
the difference between two resistance measurements when two different test
currents are applied to determine any offset voltage in the input circuitry. The
resultant displayed measurement corrects this offset, giving a more accurate
resistance measurement.
