Breakpoints 
P610-P673 Level/Volume Breakpoints 
These parameters are used to create a profile of the vessel when P600=11 
(universal linear) or P600=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 (P600=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.
