Overview of the Digital Multimeter

The Digital Multimeter (or DMM) is the Swiss Army knife of the electrician’s toolbox. The digital multimeter condenses several tools that an electrician may have needed down into a single, fairly rugged box. The multimeter changes from a Voltmeter, Ohmmeter, Ammeter, and other tools with a twist of the dial!

Below is the AstroAI digital multimeter that, as of this writing, is included with the Betabox Electrician Foundations and Futures Hands-On Project Box.

The multimeter in the kit may change. As an electrician, you will likely encounter a wide variety of multimeters in the field, often with unique tools like thermocouples or non-contact voltage detectors. One such multimeter, a model by Crenova, will be used in the lesson demonstration where needed.
