subject: How to Measure Volts, Amps and Ohms with a Digital Multimeter [print this page] To measure ohms, you will use the ohmmeter function of your digital multimeter. The first thing you must do is to disconnect the power and wiring from the circuit you wish to measure. When all is disconnected, rotate the function switch to "." Attach the red lead to the "V" terminal. Attach the black lead to the "COM" terminal.
Your display should have a readout of "OL," which indicates there is an overload. Finally, all you need to do now is connect the leads to the circuit you wish to measure to get a readout of the ohms.
In a nutshell, we have just seen how to use the voltmeter, ammeter, and ohmmeter functions of a digital multimeter. By having three essential electrical measurement functions neatly contained in one hand-held tool, you don't need to carry around three separate devices in your tool bag. Be sure to turn off your device when you are done to conserve your battery for the next time you use it.
