This value is the current pressure of the H-3551's internal air tank in psi. This value is informative
only and cannot be edited. The tank pressure should be approximately 3-5 PSI greater than the
orifice pressure.
Tank PSI = XX.X
This value is the difference between the tank pressure and the pressure on the orifice line in psi.
Like tank psi, this value cannot be edited. This value is directly proportional to the bubble rate and
should be approximately 3-5 PSI.
Diff PSI = XX.XX
This display shows the month, day any hour when the last purge sequence was made.
