What is a Digital Multimeter?
A digital multimeter is a tool used to measure multiple electrical values in a single device. Instead of carrying separate instruments, you get everything in one.
It can measure:
Voltage (AC/DC)
Current (Amps)
Resistance (Ohms)
Continuity
Advanced models also support capacitance, frequency, and temperature measurements.
