Upper limit
When this value is exceeded, the action defined in the following is trig-
gered.
The values that are actually measurable may vary from the values specified
here, depending on the hardware. The binding measurement value ranges
can be found in the "Technical specifications" chapter for the control
instrument used.
Measuring mode pH:
Input range –20.000 to 20.000
Default value 20.000
Measuring mode U:
Input range
–2000.0 to 2000.0 mV
Default value 2000.0 mV
Dosing rate:
Input range
0.00 to 166.00 mL/min
Default value 166.00 mL/min
Temperature:
Input range
–20.0 to 150.0 °C
Default value 150.0 °C
Upper hysteresis
The upper hysteresis represents the tolerance range for the upper limit
(see figure 18, page 365). When Action = Wait, the dosing does not
continue until the monitored quantity has once again fallen below the
upper limit incl. the value entered here.
The values that are actually measurable may vary from the values specified
here, depending on the hardware. The binding measurement value ranges
can be found in the "Technical specifications" chapter for the control
instrument used.
Measuring mode pH:
Input range
0.000 to 20.000
Default value 0.020
Measuring mode U:
Input range
0.0 to 2000.0 mV
Default value 2.0 mV
Dosing rate:
Input range
0.00 to 166.00 mL/min
Default value 0.20 mL/min
