Lower hysteresis
0.00 ... [ 0.20 ] ... 166.00 mL/min
(only Titrando)
The lower hysteresis represents a tolerance range for the lower limit of the
dosing rate. When the dosing rate exceeds the lower limit plus this hystere-
sis value, the action
Dosing rate lower limit ok
is triggered.
Upper limit
0.00 ... [ 166.00 ] mL/min
(Titrando)
0.00 ... [ 150.00 ] mL/min
(Titrino)
Upper limit of the dosing rate. When the dosing rate exceeds this value, the
action
Dosing rate upper limit exceeded
is triggered.
Upper hysteresis
0.00 ... [ 0.20 ] ... 166.00 mL/min
(only Titrando)
The upper hysteresis represents a tolerance range for the upper limit of the
dosing rate. When the dosing rate falls below the upper limit plus this hys-
teresis value, the action
Dosing rate upper limit ok
is triggered.
Action
D
efinition of the action to be taken when the limits of the measured value
are infringed:
Stop determination
(only Titrando)
The running
STAT
command is quit, then the exit track (if present) is started
and the determination is stopped.
Stop command
The running
STAT
command is quit, then the next command is started.
Wait for [Continue]
Reagent dosing in the current
STAT
command is interrupted and a message
appears. As soon as the monitored dosing rate is again within the limits (in-
cluding hysteresis) reagent dosing can be resumed by pressing the
[Con-
tinue]
button in this message window.
Wait for limit ok
Reagent dosing in the current
STAT
command is interrupted. As soon as the
monitored temperature is again within the limits (including hysteresis) re-
agent dosing is resumed automatically.
[ none ]
No action will be taken.
Note
If, when monitoring the dosing rate, the
Lower limit
is infringed then the actions
Wait for [Continue]
and
Wait for limit ok
are irrelevant as the mean dosing rate
becomes ever smaller during this time. The valid range can never be achieved
again.
Monitoring Temperature
on, [ off ]
If this option is switched on then the temperature will be monitored and any
limit infringements will be entered in the list of measuring points.
Lower limit
[ -20.0 ] ... 150.0 °C
(Titrando)
[ -170.0 ] ... 500.0 °C
(Titrino)
Lower limit of the temperature. When the temperature falls below this value,
the action
Temperature lower limit exceeded
is triggered.
Lower hysteresis
0.0 ... [ 0.2 ] ... 150.0 °C
(only Titrando)
The lower hysteresis represents a tolerance range for the lower limit of the
temperature. When the temperature exceeds the lower limit plus this hys-
teresis value, the action
Temperature lower limit ok
is triggered
Upper limit
