Digital Multimeter

What is a digital multimeter?

A digital multimeter (DMM) is a versatile electronic test instrument that measures multiple electrical parameters including voltage, current, and resistance. It displays numerical readings on a digital screen, making it more precise and easier to read than analog meters. DMMs typically include additional functions such as continuity testing, diode testing, and capacitance measurement, making them essential tools for electronics troubleshooting, circuit analysis, and electrical work.

Multimeter

A multimeter is a versatile electronic test instrument that measures multiple electrical quantities in a single device. It can measure voltage (AC and DC), current (amperage), and resistance (ohms), with many models also offering additional functions like continuity testing, diode testing, and capacitance measurement. Multimeters are essential tools for electronics troubleshooting, circuit analysis, and electrical maintenance, available in both analog (needle display) and digital (LCD display) versions.
