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
-20.0 ... [ 150.0 ] °C (Titrando)
-170.0 ... [ 500.0 ] °C (Titrino)
Upper limit of the temperature. When the temperature exceeds this value,
the action
Temperature upper limit exceeded is triggered.
Upper hysteresis
0.0 ... [ 0.2 ] ... 150.0 °C (only Titrando)
The upper hysteresis represents a tolerance range for the upper limit of the
temperature. When the temperature falls below the upper limit plus this hys-
teresis value, the action
Temperature upper limit ok is triggered
