Monitoring Measured value
on, [ off ]
If this option is switched on then the measured value will be monitored and
any limit infringements will be entered in the list of measuring points.
Lower limit pH
[ -20.000 ] ... 20.000 (Titrando)
[ -20.00 ] ... 20.00 (Titrino)
Lower limit of the measured value. When the measured value falls below
this value, the action
Measured value lower limit exceeded is triggered.
Lower hysteresis pH
0.000 ... [ 0.020 ] ... 20.000 (only Titrando)
The lower hysteresis represents a tolerance range for the lower limit of the
measured value. When the measured value exceeds the lower limit plus this
hysteresis value, the action
Measured value lower limit ok is triggered.
Upper limit pH
-20.000 ... [ 20.000 ] (Titrando)
-20.00 ... [ 20.00 ] (Titrino)
Upper limit of the measured value. When the measured value exceeds this
value, the action
Measured value upper limit exceeded is triggered.
Upper hysteresis pH
0.000 ... [ 0.020 ] ... 20.000 (only Titrando)
The upper hysteresis represents a tolerance range for the upper limit of the
measured value. When the measured value falls below the upper limit plus
this hysteresis value, the action
Measured value upper limit ok is triggered.
Action
Definition of the action to be taken when the limits of the measured value
are infringed:
Stop determination (only Titrando)
The running DOS command is quit, then the exit track (if present) is started
and the determination is stopped.
Stop command
The running DOS command is quit, then the next command is started.
Wait for [Continue]
Reagent dosing in the current DOS command is interrupted and a message
appears. As soon as the monitored measured value is again within the lim-
its (including hysteresis) reagent dosing can be resumed by pressing the
[Continue] button in this message window.
Wait for limit ok
Reagent dosing in the current DOS command is 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.
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.
