Measuring Resistance
Set up your multimeter to measure resistance as shown in
Figure 2- 14. Probe the test points, and read the display.

CAUTION
To avoid possible damage to your multimeter or to the equipment under
test, disconnect the circuit power and discharge all high-voltage
capacitors before measuring resistance.
NOTE
Resistance (opposition to the current flow) is measured by sending a small
current out through the test leads to the circuit under test. Because this
current flows through all possible paths between the leads, the resistance
reading represents the total resistance of all paths between the leads.
Resistance is measured in ohms (Ω).
