click the "max time" buttonThanks so much. Where can you add other tank sizes? I see the drop down (D10, D12 s80 etc) but not where I can add other tank sizes. Is there a help menu in the program?
then in the upper right "setup"
then enter in the new tank sizes, if its a single or double tanks, and their working pressures
now they will be in the drop down menus
