Multimeter, a versatile tool used for measuring various electrical properties. It is a staple for DIY electronics, automotive repair, and household electrical testing.
​Based on the photo, here is a breakdown of how this specific device works and how it is currently set up.
​1. Port Connections (The Probes)
​The probes are the wires used to touch the circuit you are testing. In your image, they are plugged into the following ports:
​COM (Black Probe): This is the "Common" or ground port. The black probe almost always stays here.
​VΩHz (Red Probe): Currently, your red probe is plugged into the far-right port. This is used for measuring Voltage (V), Resistance (Ω), and Frequency (Hz).
