To operate the high voltage power supply, first connect the AC 90~230V input, and then turn on the power. Ensure the potentiometer is set to "0" before opening
the high voltage switch. Next, adjust the potentiometer in a clockwise direction while observing the digital display value. The output voltage = the display value. When the required voltage is reached, rotate the potentiometer lock in a clockwise direction to lock the potentiometer. This will prevent accidental adjustments to the potentiometer, which could alter the output voltage. High voltage connection wire is used for high voltage output.
