With a DMM it’s okay to measure low amp draw devices such as VTX, FPV camera, or RX, but for anything that is power hungry, like motors, you should NOT use your multimeter or it might blow up the fuse. A clamp meter (buy:https://s.click.aliexpress.com/e/_DkyyHbp) is a much...
Check Voltage With a Multimeter Checking your battery’s voltage is one of the easiest ways to diagnose a no-start condition. Most vehicles need about 12.6 volts to crank the engine to life; any reading far below that will mean you may have difficulty starting up. With your multimeter ha...
Switch off the motor, and then disconnect one of the wires powering the motor. Attach your ammeter or digital multimeter set to measure DC current; attach it between the motor and the detached wire. Always wire ammeters in series with a circuit, placing them between the power source and the...
The multimeter seems to be a trusted tool for identifying shorts as well as other technical defects in virtually any electrical device. A circuit board can be quickly checked for capacitance, current, input voltage, DC & AC voltage, resistance, fuse shorts, with a multimeter. The tool is typi...
How to check a fuse with a multimeter If there is 12 Volt at both sides of the fuse, the fuse is OK. If you have a multimeter, there are two ways to check a fuse. The first way is to measure the voltage at both pins (blades) of the fuse. Small fuses in the car have the to...
