While you might want to stand there and hold the probes to the system, sometimes it’s easier to free up your hands. Using a Multimeter to test the voltage on a LiPo Battery. But if you use the 10A port to measure current, you run a much lower risk of blowing the fuse. Selection Knob Why does the meter knob read 20V and not 10V? If you’re looking to measure a voltage less than 20V, you turn to the 20V setting.


This test helps insure that connections are made correctly between two points. The surrounding components on a circuit board can greatly affect the reading. This is because the internal fuse is broken and acts as a broken wire or open. Auto-off is a great feature that is rarely seen on cheaper multimeters.

This effectively “breaks” power to the circuit. We then insert the multimeter in-line so that it can measure the current as it “flows” through to the multimeter into the bread board. The multimeter measures voltage in relation to the common probe. The first thing we’ll need is an extra piece of wire. As mentioned, we’ll need to physically interrupt the circuit to measure the current. This shopping feature will continue to load items. In order to navigate out of this carousel, please use your heading shortcut key to navigate to the next or previous heading. When measuring current, it’s often good to watch what your system does over time, for a few seconds or minutes.
