It simply causes the current reading to become negative: Current is still flowing through the system, you've just changed your perspective and now the meter reads negative. Remember: If your system has the potential to use more than 100mA you should start with the red probe plugged into the 10A port and 10A knob setting. Next, remove the two screws hiding behind the battery plate. We've seen wires come completely out of probes - and it's always at the moment you need the probes to work! But if you use the 10A port to measure current, you run a much lower risk of blowing the fuse. Multimeter icon. Macro photo, Cheerful woman holding digital multimeter near boyfriend looking at power socket. Digital multimeter. Where voltage is measure by poking at VCC and GND (in parallel), to measure current you have to physically interrupt the flow of current and put the meter in-line. There are plenty of online calculators that are easy to use.

By pinpointing what may be potentially wrong, the rework and repair of boards is made much easier. Let's drop the meter down to the next lowest setting, 2KΩ. Overloading the current can result in a blown fuse rather than just an overload display. Is a glass of water conductive? Note that almost all multimeters have the same sized jacks (they're called "banana plugs") so if you're in a pinch, you can use your friend's probes. Don't worry if you blow the fuse - we've done it dozens of times! Realize that the multimeter is acting as a piece of wire -- you've now completed the circuit, and the circuit will power on.

This shows that a very small amount of current is allowed to flow without resistance (or at least a very very small resistance) between probes. Over time the leads will tend to break down at the flex point. Two probes are plugged into two of the ports on the front of the unit. That said, don't forget to turn your meter off! Measuring from where the voltage is going in to the resistor and then where ground is on the LED, we should see the full voltage of the circuit, expected to be around 5V. Every other feature is just icing on the cake. See high-quality images selected by our team daily. The probes have a banana type connector on the end that plugs into the multimeter.
