To measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below).

Aug 29, 2022 · Now that you know the basics of resistance and why we measure it, it is time to show you how to check resistance with a multimeter. Step 1: Insert the black probe’s jack in the multimeter’s COM or common port. Insert the red probe in the ohm input port. Step 2: Select the ohmmeter function on your multimeter and select the resistance range.

When measuring resistance with an analog multimeter, switch off power to the circuit under measurement. Plug the red test lead into the positive input terminal with the “+” mark and the black test lead into the COM input terminal. Switch the instrument to Ω mode and set the range button as appropriate based on the circuit’s anticipated ...
May 2, 2019 · The only reliable way to measure resistance is to remove the component from the circuit completely and test it. If this isn’t something you’re able to do, you may have to resort to Ohm’s Law (R=V/I) to find the value. When trying to find a resistor value, you can read the color code on the resistor and use this calculator to help decipher ...
