A multimeter is an electronic measuring instrument that is used to gauge volts, amps, and resistance from an electrical source. The most common automotive application for a multimeter is to test the strength of a car battery. When used properly, it will provide voltage information to a high de...
It's a must-have for any toolbox—but there's a learning curve involved. Learn how to use a multimeter for all of your electrical testing needs.
Steps for measuring current with a digital multimeter Before getting started, it’s important to read your digital multimeter’s manual to ensure you understand how to safely use your specific model. Below are the basic steps for using a digital multimeter to measure current. ...
Theselection knoballows the user to set the multimeter to read different things such as milliamps (mA) ofcurrent,voltage(V) andresistance(Ω). Two probes are plugged into two of theportson the front of the unit.COMstands for common and is almost always connected to Ground or ‘-’ of ...
Soft soldering is a technique used to join wires, fix electronic components onto circuit boards and bond copper pipes together. This tutorial shows you how to solder step by step.
1.1—A multimeter not showing any voltage between the Hot and the Ground terminals at outlet #2 of circuit A and at neither outlet in circuit B but reading 120 Volts at outlet #1 in circuit A. 1.2—The multimeter showing 120 volts between the Hot and the white Neutral connectors on all ...
Now that you have learned how to charge your car battery, you may consider using a multimeter to test the battery in the future. A multimeter is an instrument that measures the amps and volts of the battery. If the multimeter’s digital readout indicates less than 12.2 volts, it is indic...
You should be able to read something close to 1.25 volts off the meter. It is important that you hook the black lead up to negative and the red lead up to positive and stay in the habit of doing that. Now you can use the meter to test your power supply, as well. Change the ...
You can use a multimeter to determine how much current a component draws. To perform a current measurement, the probes should be connectedin serieswith the device you are measuring. There are usually two connectors on the DMM for current measurements – one for lower current (milli-amps and ...
One interesting prototype created with the tools we'll read about on the following pages is the revolving circular waterslide pictured above. The team members on Discovery's show "Prototype This!" also attempted to create a 6x6 all terrain runner and robots that box. The "Prototype This!"...
