How to Use a Multimeter

Digital multimeters are indispensable tools that allow you to analyze circuits and diagnose problems in your electrical design. Basic models are capable of measuring voltage, current, and resistance. In this video, Shawn demonstrates the various features of a multimeter and how to appropriately take measurements in your circuits.

How to Use a Power Supply

Bench power supplies, also known as variable power supplies, are useful tools for testing and debugging circuits, as they allow you to adjust DC voltage on the fly. Some units can be configured to act as a constant current source, but in this video, Shawn shows you how to use a power supply as a constant voltage source with a configurable current limit.

How to Use an Oscilloscope

Oscilloscopes allow you to visualize how electrical signals change over time. This means you can measure periodic and transient signals, which might be too fast for your digital multimeter to catch. Oscilloscopes can be indispensable for debugging circuits.

How to Use Calipers

While they are often found in fields like mechanical engineering and metalworking, calipers have their place in electronics as well. Every now and then, I run across a component that has no datasheet, or the datasheet has incomplete information on the required PCB footprint for the part. If I happen to have the component in hand, I can pull out my trusty calipers to take whatever measurements I need from the component.
