OINT LINEARISATION
Programming 32 point linearisation % (0 … 100%) -capacitance can be assigned to the values of level and volume by data pairs. Intermediate
values will be calculated by interpolation. See the example for volume calculation:
1, Select engineering unit (
P00
).
2, Select operating mode (
P01
).
3, Programme required levels (
P05
,
P06
).
5, Assuming lower and upper level being 1 and 5 m respectively first data pair to enter in the
table is: 0% - 1 m, and the last data pair 100% - 5 m.
6, Select your tank shape (
P40
), enter dimensions (
P40
-
P45
).
