How To Use Ac Voltmeter. While most multimeters can also measure alternating current AC its not really a good idea especially if its live power since AC can be dangerous if you end up making a mistake. Today in this article we try to describe a short and helpful procedure for you to measure ac voltage with a multimeter.
Analog voltmeters use a wide variety of means to measure voltage with dArsonval moving-coil galvanometers being most common. Learn how to measure AC mains voltage with a digital multimeter. It checks alternating current AC voltage direct current DC voltage resistance and amperage.
Set your multimeter to the ohm meter function.
If the meter movement is electrostatic and thus inherently capacitive in nature a single multiplier capacitor may be connected in series to give it a greater voltage measuring range just as a series-connected multiplier resistor gives a moving-coil inherently resistive meter movement a greater. So for example calculating 12 volts on the 20-volt range will provide additional decimal places than on the 200-volt series. But when you measure the ac voltage then you should change an auto mode In custom mode. For measuring direct current ie in a battery you need to use DCV.
