A multimeter provides one of the easiest ways to measure alternating and direct current (AC & DC). We provide some of the key guidelines . . .
How to measure current with a digital multimeter Though the process of using a digital multimeter to measure current is fairly simple, it’s slightly more difficult than using a digital multimeter to measure voltage or resistance. That’s because to measure current, you need to break the circuit...
Set the digital multimeter (DMM) to measure frequency. The steps can vary by meter. Usually a multimeter’s dial will be turned to dc V and the Hz button is pressed. The DMM is ready to measure duty cycle when a percent sign (%) appears in the right side of the multimeter’s ...
When electronic engineers carry out circuit maintenance and troubleshooting, they often need to measure the diode to determine whether it is good or bad. The following are the methods and precautions for measuring diodes with a multimeter. Measure the forward resistance of the diode...
To measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turndigital multimeterdial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (con...
How to measure resistance with an digital multimeter, DMMMeasuring resistance with a digital multimeter is easier and faster than making a resistance measurement with an analogue multimeter as there is no need to zero the meter. As the digital multimeter gives a direct reading of the resistance ...
To measure battery load, conduct three voltage tests with the multimeter. Start the first test by making sure the vehicle is turned off. Multimeters have two probes: red and black. The red probe is for contact with the positive terminal and the black probe is for contact with the negative ...

Calculate the power. The power, in Watts, is equal to the voltage multiplied by the current: P = V x I Multiply the measure voltage by the measured current to obtain the power. References Airborn Electronics; Using a Multimeter; March 2011 ...
Before you proceed to measure the current with a multimeter, it is wise to have a rough estimate of the current that will be measured. This is required because the red probe needs to be connected to the correct port of the multimeter. To estimate, look for the specifications of the compon...
