METHODS
5.5.15.3 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
5.5.14.4, 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.
5.5.15.4 End Point Stability Time
This screen allows users to set the time period in which the electrode potential must remain
stable.
This setting is in accordance with the
mV end point termination criterion.
