Measuring Resistance

Set up your multimeter to measure resistance as shown in
test points and read the display.
To avoid possible damage to your multimeter or to the equipment under
CAUTION
test, disconnect the circuit power and discharge all high-voltage capacitors
before measuring resistance.
Resistance (opposition to the current flow) is measured by sending a small
NOTE
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).

Keep the following in mind when measuring resistance.
NOTE
– The test leads can add 0.1 Ω to 0.2 Ω of error to resistance measurements. To
