Today, we will be working with the most essential piece of electronic test equipment-the multimeter. We will learn how to use a multimeter and how to choose one. We’ll compare the accuracy between expensive and inexpensive meters. And I’ll try to convince you that you really need at least two multimeters on your workbench!
Multimeters are test instruments for measuring AC and DC Voltage, Current, and Resistance. Modern multimeters can measure many more parameters, including Frequency, Capacitance, Continuity, and Diode Checking. Some meters also have non-contact AC current and voltage features.
There are two objectives in this video:
1 - To learn how to use a multimeter to make various measurements.
2 - To learn how to shop for a meter and get the best value for your money.
We’ll do this by comparing five multimeters, each with a unique set of features. We'll learn how to use them, and we'll test their readings against calibrated test sources.
