Which reminds me… I emailed them last week suggesting they add 'noggle' to the OED

Before you all get lost in an english debate, we call them simply digital vernier calipers, An interesting note is, we bought one of the £10 cheapies from Aldi a while ago, now, all our gear has to pass calibration, twice a year, we put this poor little caliper through hell, it passed wirh flying colours on all scales, we use mitoyotos, i have 2 at work, and 1 failed calibration one at home, 18 month on, the Aldi cheapy is still going strong, measuring sawn off billets in the saw shop, but, we cannot use it on machining, as 1st article inspection reports have to state make and model of measuring gear, wouldnt do, would it, to see Aldi caliper on the report, lol ! Only thing we have found is the linear slides are way inferior, But for a tenner? Surprised us!

I guess that must be 'definitive' then.

I have three Aldi digital callipers, one has been in everyday use (OK three or four days a week now Iv'e retired) no problems with reliability or accuracy. The other two are going to be butchered as read outs on the lathe tailstock and Bridgeport quill. I have made a start on the tailstock one and thing look promising.

[Neil WyattModerator @neilwyatt]

In my test the Aldi one was accurate enough, but if it warms or cools the reading drifts, and by a lot, so you have to zero it regularly.

[ALAN CANTWELLParticipant @alancantwell54065]

That would be the inferior linear slides, lifting off the tracking, it loses its voltage, tighten up the two linear guide screws on the top if it has them, could you have not returned it? My mitoyo that was rejected suffered this, after only 18 months use, in a working enviroment, i got another for half price, Thing is, since its been at home, its been faultless, go figure, the tragedy of using electronic gear, is the guys do not know how to read non digital, another nail in the skills coffin,

I bought and still have an 8" "clockwork" Mitutoyo VC which cost me plenty from the tool club at my work place circa 1970's. It sits in my study desk drawer and is used rarely and only when nostalgia beckons.

However, I also have an ALDI digital economy job which I use every day simply because I do not need a magnifying glass to read it. Even so, I never rely on either of these instruments for "tolerance" work. I find that a micrometer gives a far more positive reading. Still though, I find both instruments very handy especially for measuring shallow bores compared to using a combination of internal calliper/micrometer.

[ALAN CANTWELLParticipant @alancantwell54065]

You are correct sir, the caliper is used on open limit lengths, micrometers are used for all diam measurment, including internal bowers types, plus plug gauges for bores, the caliper can be quite usefull for depths with open limits stuff, but we never use a caliper for anything under .1 mm tolerance, for this is what they are rated at, .1 mm accuracy,

Of course the productive ground for argument is calliper or caliper?

The OED lists both…

Neil

Occam's Razor would lead us to use caliper.

What do you guys call the original mechanical vernier caliper with the visible lines to be read? I have always heard them referred to simply as a "vernier". Such as "Pass me that vernier, would ya" and "Where did that bloody vernier go?" Hence if the mechanical calipers are commonly called a vernier, it makes sense that when you add a digital readout to the tool it becomes a "digital vernier".

Nobody I know ever referred to the original mechanical vernier calipers as simply "calipers". If someone asks you to pass the caliper, they want the type with two legs and a spring loaded pivot in the middle. I have never seen a digital one of them, yet.

[ALAN CANTWELLParticipant @alancantwell54065]

Refer to them as vernier, plain and simple, i still use one, its 5 foot long, Only me alone uses it,

[ALAN CANTWELLParticipant @alancantwell54065]

Oh, and no-one uses the old vernier, all scrapped long ago when digital appeared, same with mics, the ratchet is so good,  demonstrated tgat 10 guys micing up a job got the exact same reading to 1 micron, thats pretty damned good for our line of work, which is ultra high prescion, all mics and verniers are mitoyoto, superb equipment,

Strictly, the caliper is the body of the device and the "vernier" is the sub-scale used to finely divide (interpolate) the readings on the main scale (you can have verniers on lots of other measuring equipment too – including micrometers and other devices not associated with machining).

– without this sub-scale, the device is a caliper
– with the sub-scale it's a vernier caliper (often colloquially – and loosely – called a "vernier" for short)
– without the sub-scale but with a digital interpolation device, it's a digital caliper.

– "digital vernier caliper" is an oxymoron used by people who don't know any better.

…

Hence when you add a digital readout to it, it is colloquially – and quite legitimately – called a digital vernier.

Colloquialisms are how language progresses. Without them we would still be talking in monosyllabic grunts. Most words in the OED today started life as colloquialisms.

Non-sequiteurism, is that a word?

[Danny M2ZParticipant @dannym2z]

No batteries, no Vernier – maybe just the ideal present.

These are almost 40 years old and my #1goto before the micrometer leaves it's case.

[Speedy Builder5Participant @speedybuilder5]

Yes, same for me although a cheaper version. Its a pity that they don't have a way of making them read both imperial and metric though. It would need some sort of reduction gear in the dial which could be selected in or out I suppose.

[Michael GilliganParticipant @michaelgilligan61133]

A quick summary:

Caliper [or Calliper] describes a mechanical structure, and, in the current context that is something 'portable' with a pair of parallel jaws; one 'fixed' and one 'sliding'.

Vernier; Dial; Digital; Micrometer, Remote, etc. are all types of measuring and/or display system; any of which can be applied to the basic caliper.

… It only becomes difficult when colloquial usage distorts the meaning.

We keep straying from the original point ^^^

What does the young lady actually want ?

… is it the caliper, or the digital display that matters to her ?

… or [most likely] that it is "like daddies"

You mean it resembles a group of fathers?

Or did you mean "daddy's"?

Neil … That's why I very deliberately put the phrase within quotation marks.

I didn't think it would be appropriate to correct the original text.
