Concentration values:
The entered values must be strictly monotonic increasing or decreasing.
Conductivity values:
The entered values must be strictly monotonic increasing or decreasing. They must have a
minimum distance.
a) If the successive conductivity values are in the same switching range, then the minimum
distance is 0.5 % of the end value of the switching range.
b) If the successive conductivity values are in different switching ranges, then the minimum
distance is 0.5 % of the end value of the higher switching range.
If the mininum distance is not reached, then an error message is given and the table is
marked as invalid.
Switching range
0.0 ... 200.0 nS/cm
0.200 ... 2.000 µS/cm
2.00 ... 20.00 µS/cm
20.0 ... 200.0 µS/cm
After entry of a substance table, the table elements are checked for validity. The concentration
and conductivity values are checked separately.
2
The temperature values must be entered strictly monotonic increasing and with a difference of
minimum 10 K. The Tc values are not subject to check. After entry of a Tc table, it is checked
for validity.
