Resistance measurements
Set up your multimeter as shown in the figure below to per-
form resistance measurements.
Smart Ω measurements:
• Use the Smart Ω (offset compensation) function to measure
resistors affected by dc offset or leakage current.
• Smart Ω removes unexpected dc voltages within the instru-
ment, at the input, or at the circuit being measured, which
will add error to resistance measurements. Press to
switch between the bias voltage (BiAS) display or leakage
current (LEAk) display, calculated based on the bias voltage
and corrected resistance value, on the secondary display.
While performing resistance mea-
surements, press until BiAS is
shown on the secondary display to
enable the Smart Ω function.
