The PV type determines the numerical format and the
units of measure on the online PV display. Measured
PV is generally displayed in the highest decimal
precision possible to .001 and has a potentially
displayable range of 0.000 to 99999. The exceptions
are dissolved oxygen, pH, ORP and temperature,
which are displayed with fixed decimal precision. PV
Type determines specific ranges.
