I have some scales like that.
They are, in a word, unacceptable, for me.
Accuracy is +/- 0.02 / 0.03 mm.
This is unacceptable for anything remotely like precision.
Ie two pieces, with a hole in them, made with the readout
indicating the same may be off by 0.06 mm, and will normally be
off by 0.02 at least.
The holes will not be in the same place by so much that a bolt
will not fit through the two.
I am now installing glass scales, that have repeatability well
under 0.004 mm.
I doubt that the make,mark,or type of reader has anything to do
with it, ime.

?
I am strongly considering a Z axis digital linear scale
for my 7 x 16 lathe.
I am thinking I might want to mount it onto the rear side
of the bed below the saddle gibs. The scale would have a
remote reader that I could place anywhere within 48".
Has anyone done this? I like to get as much info and learn
of any experiences others may have had when doing this
mod.
Thanks
Dick
