Thread: Test Dial indicator sticking?

I picked up this Test Dial indicator second-hand off eBay and it’s a well made little device but from the rest position it has a kind of sticking point before it starts moving. In practice you’d zero the work at least a few tho in, past the sticking point so it should not affect it in operation but it concerns me. The spring is good and the needle snaps back to rest when released its just that if you gradually increase the surface contact from rest it hits a point right at the beginning, a tho in or so and then springs past it. I made this little video to show what I mean:

If they are designed like this then thats fine but if not then this may be symptomatic of a more serious problem within the mechanism. All the ones I’ve used did not stick like this but I thought I’d come here and ask if anyone has bought one that was like this by design.
Any advice welcome.
