tiamo 2.4 (for Process Analysis)
Upper hysteresis
Upper hysteresis of the dosing rate. If the dosing rate once again falls
below the upper limit by this hysteresis value, then the event Dosing rate
upper limit OK is triggered.
Titrando, 855
Input range
0.00 - 166.00 mL/min
Default value 0.20 mL/min
Action
Selection of the event to be triggered if the upper or lower limit is viola-
ted:
Selection Cancel determination | Cancel command
(Titrando only) | Wait for [Continue] | Wait for
limit ok | none
Default value none
Cancel determination
The running STAT pH command will be canceled, then the exit track
(if present) will be started and the determination will be finished.
Cancel command (Titrando only)
The running STAT pH command will be canceled, then the next com-
mand will be carried out.
Wait for [Continue]
Reagent dosing in the running STAT pH command will be interrupted
and a message will be displayed. As soon as the monitored measured
value is again within the limits (including hysteresis), reagent dosing
can be resumed by pressing [Continue] in this message box.
Wait for limit ok
Reagent dosing in the running STAT pH command will be interrupted.
As soon as the monitored measured value is again within the limits
(including hysteresis), reagent dosing will be resumed automatically.
none
No action will be taken if limits are violated.
NOTE
If the Lower limit is violated while monitoring the dosing rate, the
actions Wait for [Continue] and Wait for limit ok do not make
sense because the average dosing rate becomes smaller and smaller
during the waiting time. The valid range can never be reached again.
