Multimeter

1. Definition

A Multimeter is an electronic measuring instrument that combines several measurement functions in one unit.
It can measure voltage, current, resistance, and continuity. Advanced models also test capacitance, frequency, and temperature.

2. Types

• Analog Multimeter: Uses a moving needle on a scale.
• Digital Multimeter (DMM): Displays measurements on an LCD, more accurate and widely used.

3. Applications

• Checking battery voltage.
• Measuring current flow in circuits.
• Testing resistors and continuity.
• Diagnosing circuit faults.

4. Notes

Always start on the highest range to avoid damaging the meter.
Never measure resistance in a powered circuit.
