Measuring Resistance

Caution

To avoid possible damage to the meter or to the equipment
under test, disconnect the circuit power and discharge all
high-voltage capacitors before measuring resistance.

Resistance is an opposition to current flow. The unit of resistance is
the ohm (

Ω). The meter measures resistance by sending a small

current through the circuit.
