How Do I Test a Digital Multimeter to Ensure It Works Correctly?
To ensure your digital multimeter is functioning properly, you should perform a basic self-test and a continuity test. This is especially important if you're using it for electrical diagnostics or repairs.
- Continuity Test
- A test to determine if there is a complete path for current to flow between two points in a circuit.
- Self-test
- A built-in diagnostic function in some multimeters that checks internal components for faults.
- Turn on the multimeter and set it to the continuity mode (usually indicated by a sound wave symbol).
- Touch the two test leads together. If the multimeter beeps or shows a low resistance value, it is working correctly.
- Switch to the voltage mode and test a known power source, such as a wall outlet. If the reading is accurate, the multimeter is functioning well.
- Some models, like the digital multimeter xb, have a self-test function that you can activate from the settings menu.
I once used
a digital multimeter with a self-test function to verify its accuracy before testing a faulty circuit in my garage. The self-test confirmed the device was working, and I was able to identify the issue quickly.
What Are the Best Digital Multimeters for Advanced Electrical Work?
