Breakpoints
P1 or P2
P1-610 to 673, P2-610 to 673 Level/Volume Breakpoints
These parameters are used to create a profile of the vessel when P1-600, P2-
600=11 (universal linear) or P1-600, P2-600 = 12 (universal curved). You
should enter breakpoints in pairs, a reading for level and its corresponding
volume. The more pairs you enter, the more accurate the profile will be. In
the case of universal linear, then enter the level/volume at each of the points
where the vessel changes shape. In the case of the universal curved, enter
values around each arc tangent, as well as at the top and bottom.
You must enter at least two pairs, and you can enter up to 32 pairs.
Universal Linear (P1-600, P2-600 =11)
This volume calculation creates a linear approximation of the level/volume
relationship, and works best if the vessel has sharp angles between each
section.
You should enter a level/volume breakpoint for each place where the vessel
changes direction, and numerous where the section is slightly curved
(mostly linear, but has got a small arc). You can enter any number of pairs
between 2 and 32.
