FLOW EZ TUTORIALS - P=0 BUTTON
How to use the P=0 button of the Flow EZ™
If you need to set the pressure to 0 mbar (or 0PSI), just press the « P=0 » button. Once the button is pressed, the pressure automatically goes down to 0. If it is pressed a second time, the pressure goes back to the previous pressure setting. You can also use the « P=0 » button to power off the Flow EZ™ by pressing it for several seconds.
