Range 0.01 ... 9999.00 µL/min
Default value 5.00 (slow), 25.00 (optimal), 50.00
(fast) µL/min
Stop criterion
Stop criterion
The titration us stopped after the last dosing once the endpoint has been
reached and the stop criterion has been fulfilled. The titration can be stopped
when a particular drift has been achieved or after a preset time.
Note
The Stop conditions will always stop the titration even if the stop criterion
has not been fulfilled or has been turned off.
Selection drift | time | off
Default value drift
drift
The switch-off point will always have the same curve slope dV/dt.
time
The endpoint must be exceeded for a certain time: the Delay time. The
same Delay time with different very small volume increments (depending
on the volume of the exchange or dosing unit) means different switch-
off points.
off
The titration will not be stopped. In older instructions the Delay time
was usually defined as the Stop criterion.
Stop drift
Titration is stopped when the endpoint and the stop drift have been reached.
This parameter is only shown for Stop criterion = drift.
Range 1 ... 999 µL/min
Default value 20 µL/min
Delay time
If the endpoint has been reached, the delay time defined here is awaited
after the last dosing and then the titration is stopped. This parameter is only
shown for Stop criterion = time. The selection inf. stands for infinite.
