Somewhere I have the handbook on the Mitoyo Digimatic remote reader
head. I don't know if there is any info in there but I'll dig it out
and look.
One thing to be aware of with these and that is the update isn't that
fast. We fitted some of these scales on a grinder and had to take
them off and fit normal DRO's as the customer complained about the
slow update. Watching the display whilst infeeding meant you passed
the position you needed.
