Using these two values it is possible to determine an absolute limit for how much the flow

entered as a factor in the range 0.01 to 999900.0 (0.01ppm - 99.99 %)
The reason why there is both an up factor and a down factor is that there is typically a
desire to rapidly turn up the flow when the oxygen level is too high in the measuring area.

changes occur in the measured O
