Notes.
• If the units selected for

• Refer to Appendix A3 for further information on inferred pH.
Calculations are performed using the inputs from both sensors. Select the required
calculation from the following options:
Inf.pH(NaOH)
– Calculates a pH value in the range 7.00 to 11.00 pH based on
the type of chemical dosing and the conductivity readings.

Ratio A/B
– Calculates the ratio of the two conductivity inputs.
Difference A-B
– Calculates the difference between the two conductivity inputs.
– Calculates the amount of conductivity as a percentage that

passes through the cation exchange unit.
% Rejection
– Calculates the amount of conductivity as a percentage that is
absorbed in the cation exchange unit.
No Calculation
– No calculation is performed and the conductivity readings are
displayed directly.
