Manual Set Point Adjustment
Adjust the set point by moving the set point indicator until the line on the set point indicator is over the desired value
on the process pressure scale. Move the indicator to the right to increase the set point and to the left to decrease it.
Adjusting the set point does not affect the proportional band setting.
