The pressure at measurement or base conditions is processed as absolute pressure in the relevant
equations. In selection mode 2 of column A, however, transmitters with gauge-pressure or kg/cm2
scaling are also permitted. If these transmitters are used, the pressure at base conditions must also
be indicated in the appropriate unit. Both the pressure at measurement conditions and the pressure
at base conditions will then be converted automatically for the relevant equations.
