2 Making Measurements

Measuring Resistance, Conductance, and Testing Continuity
Set up the multimeter to measure resistance as shown in Figure 2-8. Then probe
the test points (by shunting the resistor) and read the display.
Smart Ω
Using the offset compensation method, Smart Ω 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.
Disconnect circuit power and discharge all high-voltage capacitors before
measuring resistance or conductance, or testing circuit continuity, to avoid
damaging the multimeter or the device under test.
Press to scroll through audible continuity test ( or , depending on
Setup configuration), conductance measurement ( ), and resistance
measurement ( , , or ) as shown in Figure 2-9 on page 67.
