4. If the LED next to the button is not already lit, press the
button once and the voltage display will show the measured
voltage at the output, which may fluctuate slightly from the
voltage value entered in the previous step.
5. (Optional) You may also verify the output voltage by connecting
the (+) and (-) terminals on the rear panel to an external
voltmeter. The measured value should match or be within the
entered voltage value.
Current Check
Follow the steps below to check current output of the power supply.
