problem with digital vernier

I'd love to see a 'Digivern' one day, anyone got one?

Oh, and BTW the Bronze 'spring' appears to be a gib held in place with two grub screws, one of which locates into a hole in one end to stop it sliding out and the other takes out any slop in the slider. (M&W 6" Vernier Caliper, Mitutoyo 6" digital caliper)

The apprentices have just taken the M&W apart to see how it works!!

Russell I see where you're coming from my original comment was in response to 'hold it in your hands to warm it up' I agree normal battery changing should not degrade the battery noticeable. I wear gloves when handling coin cell out habit from my job

Thank you kindly for your interpretation Bogs, I'm sure you will realise what you have said, one day.

Lofty,

Not sure if you saw my post on 13th ^^

I must admit, I had hoped for some feedback ... even if only ridicule.

MichaelG, Yes I did see it thanks, and like you was expecting a few more to think about the terminology..

I suppose that calling a digital caliper a vernier caliper, (or 'digivern' can be likened to every vacuum cleaner being called a Hoover.

Pierre Vernier (1580 – 1637) will be rolling in his grave.

Standard name for a Ball Pein hammer was a Persuader when I was at work.

I guess that's Mr Pein rolling in his grave too. Tee Hee

We / I used to have to get five people to measure a part five times to get a mean for capability studies. We gave up using verniers on the factory floor and used go no go gauges instead. Most people stole the verniers or used them to open cans prop open doors or they might try to stick the sharp ends in wood when used like a tomahawk.

Oh happy days... no wonder I'm grey.

Interesting that the NPL uses the spelling 'calliper'.

It just goes to shew that it is our 'National' Physical Laboratory.

MichaelG.

But why two different spellings in the same document ?

Les,

I think you will find that NPL's document is consistent in its spelling [except in Appendix B, where a hyperlink is quoted]

Neil's uncredited image appears to be from another source.

Hi Michael,
I assumed that the image Neil posted was from an NPL document.

Les,

Never assume

To be honest, I was surprised that the google embed code didn't automatically brand it!
