The actual (uncompensated) conductivity limits are in accordance with the specifications set
forth in the method "<645> Water Conductivity" of the USP 25–NF 20 (January 2002).

The actual sample water temperature is rounded downward to the nearest 5° to establish the
conductivity limit, thereby assuring any potential excursions are detected early. For example,
if the measured water temperature is 24.5 °C, the 20 °C limit is applied and an alarm is
generated if the conductivity exceeds 1.1 μS/cm U.
To ensure agreement between all data outputs, TOC, conductivity, and temperature values
are all rounded to match the analyzer's accuracy for alarm limit checking, display, printouts,
and any digital outputs.
