Pharmaceutical water
Here you can make settings for monitoring pharmaceutical water
in accordance with the United States Pharmacopoeia (USP) or
European Pharmacopoeia (EP).
The uncompensated conductivity value and the temperature are
measured for the limit functions. The measured values are
compared against the tables defined in the standards. An alarm is
triggered if the limit value is exceeded. Furthermore, you can also
set a preliminary alarm (warning limit) which signals undesired
operating states before they occur.
