Min. rate
This parameter defines the minimum rate with which bromine is gener-
ated inside the Control range. The smaller the rate the slower the titra-
tion and the higher the accuracy.
Input range 1.0 - 999.0 µg/min
Default value 15.0 (slow), 25.0 (optimal), 50.0 (fast) µg/min
Selection minimum
Stop criterion
Stop criterion
Switches off titration when the endpoint has been reached and the stop
criterion has been met.
Selection Drift | rel. drift | Time | drift & time | off
Default value drift & time
Stop drift
The titration is stopped when the endpoint and the stop drift have been
reached. This parameter is only shown for Stop criterion = drift or drift
& time.
Input range 1 - 999 µg/min
Default value 15 µg/min
Relative stop drift
The titration is stopped when the endpoint and the stop drift have been
reached. The stop drift is the sum of the drift at the titration start and the
relative stop drift defined here. This parameter is only shown for Stop cri-
terion = rel. drift.
Input range 0 - 999 µg/min
Default value 5 µg/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 or drift & time.
Input range 0 - 999 s
Default value 40 s
