Use multimeter pdf

DC fundamentals and network theorems are also integral part of this book. Electromagnetism, magnetism and electrostatics are best described in this book. Other topics like AC fundamentals assonance, transformers, fitters and coupling circuits have also been discussed in this book, Vacuum Tubes BJT, special diodes, FET, diodes and applications, thruster and special diodes have been explained in this book.

One can click and download the above said topics. Millimeters have two kinds, analog and digital. Mostly digital Millimeters are used. Liquid crystal technology is used in these meters to get accuracy in readings. Higher input impedances is other benefit. Electronic Device and Circuits:. Electronic — the Engineering branch conducts the study of flow and control of the equipment or device controlling the electrons flow is named as elonic device.

How Do I use Digital Millimeters? Here surely you will learn the use of Digital Multimeter. This is an integral tool in dealing the electronic circuits and even to check a battery. Place the red probe on the positive terminal, and the black probe on the negative terminal. If your range was set too high, you may not get a very accurate reading. Here the multimeter reads 9 volts.

That's fine, but we can turn the dial to a lower range to get a better reading. If you set the range too low, the multimeter simply reads 1 or OL, indicating that it is overloaded or out of range. This won't hurt the multimeter, but we need to set the dial to a higher range. Remember that you'll be testing the resistance of the entire circuit.

If you want to test an individual component such as a resistor, test it by itself—not with it soldered in place! Most multimeters are not autoranging, meaning you will need to set the correct range for the resistance you expect to measure. If you're not sure, start with the highest setting.

If your multimeter reads close to zero, the range is set too high for a good measurement. Turn the dial to a lower setting. The other possibility is that the circuit or component you are testing doesn't have continuity —that is, it has infinite resistance.

A non continuous circuit will always read 1 or OL on a resistance test. Cancel: I did not complete this guide. Badges: Fix Your Stuff Community Store. Difficulty Moderate.

Thank you for your interest. Thank you for the basic tutorial in learning how to use a multi meter. That was awesome. I was able to comprehend the basics I needed to know.

Selecting a multimeter You can find a wide variety of multimeters with different functionalities and accuracy. Getting familiar with a multimeter A multimeter is composed by four essential sections: Display : this is where the measurements are displayed Selection knob : this selects what you want to measure Ports : this is where you plug in the probes Probes : a multimeter comes with two probes.

Generally one is red and the other is black. So, assuming the convention: the black probe is always connected to the COM port. The V with a straight line means DC voltage. The V with the wavy line means AC voltage. Make sure the red probe is connected to the port with a V next to it.

Connect the red probe to the positive side of your component, which is where the current is coming from. Connect the COM probe to the other side of your component. Read the value on the display. What happens if you switch the red and the black probe? To measure the voltage drop across the resistor: You just have to place the red probe in one lead of the resistor and the black probe on the other lead of the resistor.
