Well there is,

You may be looking for something like another DIN indicator, which you
won't find - nothing like that.

The idea is that when the binding length is properly set, the boot sole
is slightly longer than the toe-heel distance of the binding - when you
click into the binding the heel piece moves rearward slightly to
compensate. How much it moves rearward is carefully controlled, for the
release functions depend on this pressure. So the manufacturers put a
mark on one piece of the heel binding and a range on the other piece and
when the boot is clicked in the mark must be within the range. This can
be as complex as actual grooves etched into the metal (or molded into
the plastic) or as simple as a particular screw or rivet lining up with
another - different for every binding and a function of design, not of
DIN requirements. If the heel piece doesn't move into the proper preload
range the binding release function is compromised.
