Using a multimeter

This port allows the measurement of current (up to 200mA), voltage (V), and resistance (Ω). This allows for different types of probes to be used. The most basic things we measure are voltage and current.

It will also explain the basics of electricity and address . A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits.

This instrument will let you check to see if there is.

You can also use it for checking continuity of wires and fuses.

If you like to DIY, do car maintenance or troubleshoot electronic or electrical . Set the multimeter to “2V” in the DC (direct current) range. Almost all portable electronics use direct current), not alternating current. Continuity testing is the act of testing the resistance between two points. Reading current is one of the trickiest and most insightful readings in the world of embedded electronics.

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 . Normal resistors have color codes on them. There are plenty of online calculators that are easy to use. However, if you ever find yourself without internet access, a multimeter is very handy at measuring resistance. A multimeter is used to make various electrical measurements, such as AC and DC voltage, AC and DC current, and resistance. Multimeters may also have other functions, such as diode and continuity . Turn the dial to Continuity Test mode ( continuity ). If require press the continuity button.

First insert the black test lead into the COM . Supply, Service Range, Point of Use Range. Satisfactory, Acceptable, Satisfactory. Some also test diodes and continuity.

Once you are able to test circuits, you will understand better how they work and be able to locate and correct faults.
