What does a digital multimeter measure?

A digital multimeter is a versatile instrument that is primarily designed to measure electrical parameters such as voltage, current, and resistance. Each of these measurements plays a crucial role in electrical troubleshooting and testing.

Voltage measurements allow technicians to determine the electrical potential difference between two points in a circuit, which is essential for identifying whether an electrical system is operating correctly. Current measurements help assess the flow of electrons through a circuit, ensuring that devices are receiving the proper amount of electricity. Resistance measurements are vital for evaluating the integrity of circuits and components, allowing technicians to identify and troubleshoot issues such as shorts or breaks.

While other instruments may measure frequency, phase, temperature, humidity, and even weight, a digital multimeter focuses on the three fundamental electrical measurements that are critical for electrical work. This specialization is what makes the digital multimeter an indispensable tool for electricians and technicians in the field.
