4.6.3.5 Stop delay time
Is the time in seconds in which the drift-stop criteria are being checked. The «stop delay time» can be set
between 0 and 60 seconds. The pre-set standard value is 5 s (Fig. 77).

4.6.3.6 Working point
The «working point» in mV is the base value for the indicator electrode. It can be set from 1 to 1000 mV. 300
mV is pre-set as standard value and works for many reagent/reagent combinations. A higher value is maybe
sometimes necessary (Fig. 78).

4.6.3.7 Stop Drift (delta)
The «stop drift» in µg/min is not an absolute end value. The end value of a titration is always the currently
measured drift + stop drift (Fig. 79).
