5.4.6. Linearization
P47: - - - a Linearization
Linearization is the method of assigning a (calibrated or calculated) level or volume to values measured by the transmitter. Data pairs of the
linearization table are handled in a 2x32 matrix, consisting of two columns. Between the entered data pairs the unit calculates the output value
from the measured level by linear interpolation. It can be used for (LEVEL VOLUME) instance if the tank shape is other type than the pre-
programmed shapes (P41 ... P45).

P48: - - - - Linearization table
The data pairs determining the linearization characteristics are stored in a two-column table. The table can be filled with pre-calculated values or
measured data while filling the silo. The unit gives an address
(i) to the data pairs.
The left column (indicated on the display as “ L ”) contains the measured LEVEL values.
The right column (indicated on the display as “ r ”) contains the calibrated values interpreted according to the selected measurement value in
P01(a).
