How to use 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. Set the multimeter to “2V” in the DC (direct current) range.

Almost all portable electronics use direct current), not alternating current. It will also explain the basics of electricity and address .

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 . Continuity testing is the act of testing the resistance between two points. 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 . Wanna start diagnosing some of those electrical system gremlins yourself? DC, AC, Current, Voltage, Resistane, hfe of transistor. The most basic things we measure are voltage and current.

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. Using certain multimeter models, you can test to be sure that components — such as diodes, capacitors, and transistors — function properly. A multimeter is an electronics testing device that, um, tests multiple things, including resistance, voltage, and current.

Most electricians today use digital multimeters.
