WebFeb 23, 2024 · 1. Set the multimeter to Ohms or Resistance. Turn the meter on if it has a separate power switch. When multimeter measures resistance in ohms, it can not measure continuity because resistance and continuity are opposites. When there is little resistance, there will be a great deal of continuity, and vice versa. WebApr 25, 2024 · Using Ohm's Law The voltage (V), current (I) and resistance (R) of a circuit are related by Ohm's Law, a simple equation that states: V = I•R. Multimeters employ this law when measuring ohms, which are the units of resistance, by generating a current through the circuit by means of an internal battery.
