Electronical Pressure Control Digital Display for DP-6337iB Electric Airless Paint Sprayer

Answer: following the below step to adjust

1. Turn off the spray gun under the machine is working state, when the machine is stopped, to see the mechanical pressure (for example 21),then to see the electronic pressure(for example 25.6)
2. There is a red button on the opposite side of electronic pressure display, see below picture.press it with your finger then look at the number of electronic pressure display to go up or down. If it is going up,release the finger and repress again at once. Keep pressing and now the number begin to go down and will go down faster and faster. Until the number go down as you want then release the red button.
3. In the process of adjusting the number in the red button of the electronic display,each time the button is pressed, the number in the display will reverse walking. The longer the pressing time, the faster the number changes,and can repeatedly pressed until the pressure is same with mechanical pressure gauge.(Normally we recommend that it is better for electronic pressure is slightly more than the mechanical pressure)
