This video will show you how to properly use a multimeter.

Here are some common functions and measurements performed by a multimeter:
Voltage Measurement: Multimeters can measure direct current (DC) and alternating current (AC) voltages. They are useful for checking battery voltage, power supply output, or voltage drops across components in a circuit.
Current Measurement: Multimeters can measure the flow of electrical current. They have different current measurement ranges to handle various current levels, from milliamperes (mA) to amperes (A). Current measurements are typically done by interrupting the circuit and connecting the multimeter in series with the component being tested.
Resistance Measurement: Multimeters can measure the resistance of resistors, components, or entire circuits. This feature is handy for testing the continuity of wires or checking if a resistor is within its specified value.
Continuity Testing: This function checks if there is a continuous path for current flow between two points. It is commonly used to identify broken wires or faulty connections.
Diode Testing: Multimeters can test diodes to determine if they are functioning correctly. Diodes are electronic components that allow current to flow in one direction but block it in the opposite direction.
Capacitance Measurement: Some multimeters have the capability to measure capacitance, which is the ability of a component to store electrical charge. This feature is useful for testing capacitors or identifying their values.
Frequency Measurement: Advanced multimeters may offer the ability to measure the frequency of electrical signals, which is particularly useful in electronics and telecommunications
Multimeters come in different types and models, ranging from basic analog meters to more advanced digital models. They are widely used by appliance repair technician, electricians, electronics technicians, hobbyists, and anyone working with electrical or electronic systems.
