Linearization
26 71 - 2 … 75 - 2
Determination of the index markers
Gauging the level in litres
- mode 40: coordinate display 1 to level 1
- mode 99: select linearization curve 4
- fill or empty step by step with part volume
- note the respectively measured values for H %
(level percentage) of display 1 on the linearity
protocol
- the respective value for L % (volume percen-
tage) should be calculated as follows
100 % x part volume1 (…32)
L % = ––––––––––––––––––––––––
vessel volume
e.g. volume percentage for 1 part volume:
100 % x 5 m 3
L % = –––––––––––– = 5 % (acc. to example)
100 m 3
- note the calculated values for L % in the linearity
protocol
- continue the procedure of "gauging the level in
litres" with the same part volume until H 100 %
and L 100 % as described above.
- Attention:
The linearization curves must ALWAYS be
finished with H 100 % and L 100 %. This finish
can be programmed after any number of index
markers.
