The value pairs in the dip table can be read and written. You can enter the measured
value and the dip value.
–uncorrected measured value:
This is the measured value supplied by the instrument,
NOT
corrected by the dip
table. The choice of measured value, level or remaining fill height is dependent on
the instrument setting.
–Dip value:
This is the level or distance to flange respectively, given by the hand dip. This value
should be used to correct the measured value.
The "manual mode" of the dip table can be used to enter collected data after a series
of data pairs taken at different tank levels.
Note!
The bigger the distance between the different levels while taking hand dips, the more
accurate the linearization of the dip table will be.
