What is a Digital multimeter?

A digital multimeter (DMM) is a versatile electronic measuring instrument used to measure voltage, current, resistance, and other electrical properties. Unlike analog multimeters, it uses a digital display, providing clear numerical readings that are easy to interpret and more accurate. Digital multimeters can measure both DC and AC voltage, current, and resistance, and often include additional features such as diode testing and continuity testing. They are commonly used for repairing and maintaining electronic devices, testing circuits, and troubleshooting electrical issues. Due to their ease of use, digital multimeters are suitable for both beginners and experts in the field.

Application of Digital multimeter

✅Repairing Electronic Devices
A digital multimeter is an essential tool for diagnosing faults in electronic devices. For example, it can measure voltage and resistance in household appliances to identify faulty components.
✅Testing Circuits
When assembling a new circuit, a digital multimeter is used to measure voltage and current to verify that the circuit is functioning properly.
✅Troubleshooting Electrical Wiring
When electrical wiring in a house or factory has problems, a digital multimeter is used for continuity testing to locate open or short circuits.
✅Testing Batteries
Digital multimeters can be used to check the voltage of batteries in vehicles or electronic devices to determine if they are functioning properly.
