Calipers, a feature I didn't knew

[PEU]

Decades using calipers and a few days ago I was told about something I didn't knew.
What do you do when you need to measure a piece height thats over a table for example, you use the little bar that sticks out from the end of the caliper.
Well, there is a better way that most of the modern calipers have, photos speak for themselves.

The caliper on the left is an old TESA, it does not have this feature, I was told that ETALON was the first one that introduced this capability in the 70's.

Yes, that is a handy feature. I use it often.

The advantage of using the back of the head over using the little depth gage bar is that the end is flat and broad and so you don't have problems with readings that are too long due to tilting the caliper. I think of it as a height gage.

All you have to do to that Tesa is to measure the offset and add that mentally to the height each time.

Nice tip Pablo. I've never seen that done & had not thought about using the head instead of the depth rod.

Thanks for sharing. I've been using calipers most of my life without knowing this. Cheers.

This rang a bell, so I did some searching. I finally found it in the "Silly Newbie tricks" thread.

Look for the "Ledges" paragraph.

Gracias Pablo.

Yup, great feature. I use that on my Mitus often when chucking stock, I place it up against the jaw face.

You can also use the thin metal bit that slides out from the far end as a way to measure the depth of boreholes.

After 30+ years doing it as a hobby, and some time in a pro shop, and I never knew that. Thanks!

Interesting to know as I work in calibration lab and we do check that measurement is in specification but not many people knew about it.

Cool to know, do you do calibration for hardness testers? after a lot of pain I calibrated mine to a point Im satisfied, but you may have insight on better procedures or more checkpoints.
