If you're measuring the resistance of an ignition coil's secondary winding, and it's supposed to clock in at, say, 8,000 ohms, you'd want to set the multimeter to the number one step higher than that.

A multimeter or digital multimeter (DMM) is one of the most essential and common pieces of lab equipment. Multimeters are used for taking basic electrical measurements related to Ohm’s Law.

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.
