How to Use a Multimeter to Test Fault Points on a Circuit Board

A multimeter is a versatile measuring tool designed primarily for measuring voltage, current, and resistance. It is an essential tool for diagnosing and troubleshooting electrical issues on circuit boards.

When using a multimeter to test fault points on a circuit board, it is important to follow these steps:

• Set the multimeter to the appropriate mode (voltage, current, or resistance).
• Ensure the circuit board is powered off before testing.
• Place the multimeter probes on the points you want to test.
• Read the measurement displayed on the multimeter.
• Compare the measurement to the expected values to identify any faults.
