Voltage - Adjust
Note: This procedure does not apply to an external potentiometer for voltage adjustment.
Note: The R250 AVR must be set for the correct output frequency before the output voltage is adjusted.
Ensure that a jumper is Installed across "ST4". Rotate the voltage adjustment "P1" in a clockwise direction in order to increase the voltage. Rotate the voltage adjustment "P1" in the counterclockwise direction in order to decrease the voltage.
