6.5.4 Consistency check of
concentration value
The instrument automatically performs a
consistency check as the value pairs for
concentration and conductivity and the
corresponding temperature coefficients are
entered.
This consistency check is performed following
each input or change of a value and is
triggered by pressing either the V key or the
V and H keys together.
During the consistency check, the instrument
checks the following:
• are the conductivity values arranged in an
ascending or descending order,
• is the difference between conductivity
values min.
1
/
200
of the measuring range,
• is the span min.
1
/
5
of the measuring range,
• are the temperature values entered in
ascending order, and is their minimum
difference 10 K.
If an error is detected, the corresponding
alarm messages 93 to 96 are issued (see
error list in chapter 7.3), and the display
changes in matrix field V6 / H0.
If all values entered are valid, the instrument
checks the values stored in matrix fields
V5 / H1 to V5 / H7 for correct assignment to
the substance concentrations.
If the values stored in matrix fields V5 / H1 to
V5 / H7 are outside the range limits, the
values are automatically adapted to the range
limits and overwritten.
Note:
There is no measured value display
during this check and adaptation.
