I have a Chinese digital caliper that the tips have somehow become magnetized.
Question: Will pulling it thru a demagnetizer destroy it?
I’ve tried cautiously putting just the tips in the demagnetizer.  It weakened the magnetism and didn’t seem to affect the operation, but I am a bit leery about demagnetizing the entire caliper.
I posed this question on another forum but no one knew for sure.
Thanks for any info.

Usually they have capacitive sensors (some have resistive I think), so I don't think a magnetic field can harm it. Only way to know for sure is to try it

Hi Daniel, I can’t tolerate magnetized tools so I bit the bullet and gave the calipers the full treatment. Good news, you were right, it didn’t do any harm. And now I can say from experience that they (at least this one example) can be safely demagnetized.

Come on now, Al..........without the little metallic fuzzes on the calipers i personally would never be able to tell
if the measurements taken were North, South, East or West.......

Glad it worked out fine for you, Al. And now we have an answer to this question as well
