Calculation Units
Factory default value for P02 is: 000
Engineering units for volume are selected in "b", and units
for open channel flow are selected using "b" and "c".
Metric or US for "b" is selected by the value of "c" in P00.
The volume can also be displayed in units of weight by
setting "b" and entering the density of the fluid in P32.
The value of "a" determines the temperature units when
the UP
key is pressed in the operating mode.
