Q:

How do you use a multimeter?

A:

Quick Answer

To measure resistance on a multimeter, switch the device to ohms or resistance, and find the scale that measures resistance. Attach the test leads to the corresponding jacks, hold the ends of the test leads together, and set the zero adjust knob to zero. Find the electrical contact points of the appliance the resistance of which you want to measure, press the two probes of the multimeter to them, and observe the value indicated on the scale.

To measure voltage, set the device to the highest value of volts that is possible, attach the test probes to the jacks, and find the voltage scales. Connect the probes to your device and note the voltage that the scale indicates. Disconnect the probes, reset the voltage knob to the lowest range offered that is greater than the voltage value that was measured, and attach the probes again. This helps you to get more accurate results. If the device indicates zero volts, switch the device between AC and DC modes.

To measure current, set the device to the maximum AC or DC amperes value, and include the multimeter and a "clamp-on" ammeter into the circuit in series. Note the polarity and the value indicated on the scale.

Before using a multimeter, make sure that you are familiar with all of its parts, their functions and their locations.
