I am more likely to suspect the calipers than interference.? Especially if they are the extremely inexpensive ones.

?

But it would be easy enough to drive the calipers a distance away from any electrical transmission source and see if they magically start working.

?

I have some of the low-cost digital calipers and mine have a tendency to skip sometimes and suddenly be 0.2 or 0.4 inches off or something) and also?

?

I finally bought two Mitutoyo digital calipers, 4 inch and 6 inches.? NO problems - ever.? Yes, they cost a bit.? In the long run, I think a better value.? I also have some dial calipers I sometimes use.

?

And just to be pedantic, if it is a digital caliper, then it is not a vernier.? Those are two types of calipers.? One has a digital scale.? The other a vernier (where you line up physical marks to read accurately).? Although many people still include the word "vernier" even if it doesn't fit - even listings for sale.? You have vernier, dial, and digital.

I can not work without many "Digital Electronic Vernier Caliper" in my workshop.

However, they are always hiding them self when I am doing my job.

Lately I have discovered that they are missing the numbers on the display.

Both old and new ones.

Suddenly the numbers are being negative or shutting down.

I am blaming a Comunicacion tower not far?from the building.

Someone's that has a good advice for me?
