How do you test voltage and amperage output on a cathodic protection rectifier?

To test the voltage and amperage output on a cathodic protection rectifier, first, ensure the system is safely powered and properly isolated. Use a multimeter set to the appropriate voltage range to measure the output voltage across the rectifier terminals. For amperage, utilize a clamp meter or connect a current meter in series with the output circuit to measure the output current. Always follow safety protocols and manufacturer guidelines while conducting these tests.
