Once these principles are clearly understood, static problems become just like the many other technic problems that skilled technologists, scientists engineers solve every day by taking meaningful measurements, analyzing the results, and applying the fundamental principles. I invite you to send me your ...
A digital multimeter (DMM) is one of the most useful test instruments in any automotive electrician's tool kit. Every DMM is slightly different but there are some general guidelines you can follow for its use. An old analog voltmeter will work too but be careful of polarity when using one ...
so if you're going to use a voltmeter on any 12V system or power source, this is the most likely candidate. Although you can use a dedicated voltmeter for this, you're more likely to use a multimeter. Measuring voltage is only one of its functions. The others are measuring...
Testing voltage follows a simple process. For those of you new to electrical testing, we asked our resident Pro how they might teach an apprentice how to use a multimeter or voltmeter. Once you know how to use a multimeter, you can move on totroubleshooting and fixing electrical problems, ...
A multimeter is a measurement tool absolutely necessary in electronics. It combines three essential features: a voltmeter, ohmeter, and ammeter, and in some cases continuity. A multimeter allows you to understand what is going on in your circuits. Whenever something in your circuit isn’t working...
All riding lawn mowers run on the same type of 12-volt circuit that an automobile runs on, and some of the parts are nearly interchangeable, such as the solenoid and starter. Attach the negative probe leading off of your voltmeter to either the chassis, a negative ground wire or the negat...
Analog testers allow you to make intuitive judgments based on the deflection of a needle on a graduated scale. They measure a simple selection of parameters, and they have the advantage of being easy to use. On the flip side, they have the disadvantage of having large instrument loss. Digita...
There are two ways to check a light socket with a voltmeter. The first is to check the voltage. You can do this with the power on and the bulb removed. The second way is to test continuity or resistance. For this test, the power must be off and the light
How to Use (and Choose) a Multimeter!: Checking your car battery life, debugging circuits, and finding that pesky short are all super useful functions that can be done with just one awesome tool: the multimeter! First of all, what the heck is a multimete
