to the “zero” position given in the cylinder drawing.
To do this, it’s first required to know L
t0
(=length of pushing
tube which is visible when cylinder is in the “zero” position
on the cylinder drawing – please have a look at the cylinder
drawing) – as examples, see below some drawings illustrat-
ing L

Then, it’s required to measure L

when cylinder is in any position.
