METHODS

5.5.11.3 Termination Criterion

This screen allows the user to set the titration termination criterion.

mV End Point

The titration is terminated when the potential remains below a set mV

value for a specified period of time (see Section

5.5.11.4, End Point

Stability Time).

Absolute Drift

The titration is terminated when the actual drift is less than the

predefined absolute drift value.

Relative Drift

The titration is terminated when the actual drift is less than the sum

between the initial drift and the predefined relative drift.

5.5.11.2 Maximum Water Titrated

The maximum water reacted during the titration must be set according to the analysis.

If the titration end point is not reached, the titration will be terminated after the maximum

titrated water has been reacted. The error message (“Limits Exceeded”) will appear on the

display.

Range is from 0.1 to 100.0 mg.
