• 2-circuit device: There are two possibilities to put the difference between two pH
values on the current outputs:
– Delta pH as value on current output
If the current outputs are only defined via positive delta pH values, the negative
differences are output as value (see table column 1).
INFO
Entry of the upper and lower measured value limits
The maximum measured value range is
–2 ... +16 pH.
The minimum distance from the upper to the lower
measured value limit is 2 pH units.
(Example.: 0/4 mA: pH 7 and 20 mA: pH 9)
Note in display:
The linear characteristic is activated after confirmation
by pressing "E". Cancel by pressing "PARAM".
Entry of the number of support points (value pairs)
Value pair entry
pH/Redox/°C - mA (number of required value pairs =
number of support points desired in Field EAB1).
Selection:
Are the value pairs OK or do you want to delete
elements?
Delete:
Select the row to be deleted, delete with
confirm by pressing "E".
Note in display (no entry)
Table status If invalid, then back to EAB4.
Note in display:
The table is active after confirmation by pressing "E".
Cancel by pressing "PARAM".
