How do you Check Voltage on a Multimeter?

As stated earlier on, the accurate voltage measurement is a must-have feature on any multimeter.

 In order for you to do this conveniently, you should first power off the device completely. So as to be certain that there is no electrical current flowing through it, you should also discharge any capacitors present on the circuit.

Having disconnected the multimeter from any power source, go ahead and have the banana jack of the red probe plugged into the port that is marked with a ‘V’ which in some cases is marked with the Omega symbol. The black probe, as usual, should be in the COM port.

The Beginners Guide

Once again, if the multimeter is a manual ranging one, you should be specific on the voltage. Dial it to either DC or AC voltage. If the multimeter, on the other hand, is an auto-ranging one, just have the red probe plugged into the correct port and the multimeter will automatically detect whether its DC or AC.

With the black probe being the neutral or negative one and the red one being the live one, go ahead and connect these two in parallel with the circuit. Touch the black probe first at the first point, power up the device then touch the red probe on the opposite end.

At the same time, as you power up the device, you should observe all the safety precautions such as being careful not to touch the metallic tips on the probes. Take the measurement on the LCD screen and you’re good to go.
