How do you check nonisolated led driver?

To check a non-isolated LED driver, first ensure the power is disconnected for safety. Then, use a multimeter to measure the output voltage and current while the driver is powered on, confirming it matches the specifications. Additionally, inspect the driver for any visible signs of damage, such as burnt components or unusual heat. If necessary, perform a continuity test on the connections and verify that the LED load is functioning properly.
