1) Turn the ten-turn potentiometer between five to seven turns clockwise or just until you feel a small click - signifying the full span of the pot.
2) Start the generator set. You will notice the overspeed calibration LED illuminated.
3) Slowly turn the potentiometer counter-clockwise until the LED just turns off.
5)    As soon as the LED turns off, start to slowly turn back the potentiometer clockwise just until the led starts to flicker.

Your generator overspeed setpoint is now calibrated!
