For instance, a reading that says 4. 3 with only the omega symbol indicates 4. 3 ohms. A reading that says 4. 3 with a “K” before the omega symbol means 4. 3 kilo-ohms (4,300 ohms).
Resistance is a measure of how much a device or material reduces the electric current flowing through it. Higher numbers indicate a higher resistance rating, which means more energy will be required to integrate the component in a circuit. When you test a resistor, capacitor, or another electronic component, the ohmmeter will display a number indicating its resistance.
Consult manufacturer directions for more information about how to select the resistance function on your multimeter.

The precise method by which you remove individual components depends on what the component is. For instance, if you’re testing a capacitor, you’ll need to remove it with a soldering iron and discharge any remaining electrical energy from it.
Even within the same type of component, the placement of these leads varies. For instance, in some capacitors, the leads both exit the same side. In other capacitors, one lead will poke out of one end while the second lead pokes out the opposite end. If you’re having trouble identifying the leads of the component you’re interested in testing, consult manufacturer directions. It doesn’t matter which test lead and which component lead you touch together.
The auto range setting might be inbuilt, or you might need to select it from a menu. Consult your user guide for more information.
If you set an analog ohmmeter’s range too low, it will cause the needle to snap rapidly to one side, potentially damaging it.
If you make adjustments to the ohmmeter’s range, you may need to calculate the ohms using multiplication or division. Follow the instructions for your ohmmeter carefully to learn how to adjust your measurements.
