Performing Resistance Measurements
Measuring resistance
1 Press . The default function is 2- wire W measurement.
2 Connect the red and black test leads to the input terminal as shown in
Figure 2- 6 or Figure 2- 7 respectively (according to the selected
measurement method).
3 Probe the test points (by shunting the resistor) and read the display.
In autoranging mode, the multimeter automatically selects the appropriate
range and the measurement is displayed.
