Hi. I’ve borrowed / used digi callipers before but I recently picked up a couple of my own.
A dead model 500-191 ( black scale in photo), I got this as non-working project, described very honestly as "it could be genuine or could be a clone". History is unknown.
The contacts were cleaned, tensioned and I fitted a new battery - it still shows no sign of life.
Any suggestions / common problems / any diy guides to open these up?
The model 500-311 is now working but don’t ask how long I spent trying to fit the battery into the “external readout” port. Oops !
General question. How do you clean these and where is the actual “scale”? Both have light dirt on them and I’d like to freshen them up.
Thanks to @sako243 , @fizzy and @roblane65 for their help getting me this far
