I have replaced this image with better quality ones from German wikipedia which have a greater explanatory value.

message: linear vs logarithmic, not linear vs angular. this should be clarified
I don't understand how the zero point of the vernier/indicating scale is coincident with the start of the data scale. It is coincident with the index of the "slider".
:I have added some clarifications to the article which I hope explains things. Please come back if its not clear as this dialogue can only improve the article for new readers. Lumos3 13:22, 24 September 2005 (UTC)
replies: text: Perhaps it is also worth noting that at Zero (or any exact alignment of the vernier 0 with a main scale mark, the Vernier end (9 or 11) mark is also aligned.  This double alighment is also one indication of scale quality (If four marks don't align everywhere, don't buy it!)<BR>
A Vernier scale also makes it easier to guess at another additional decimal of precision with reasonable accuracy, as you can see when none of the marks align, the true measure is between the two vernier marks that are enclosed by (or enclose) 2 marks on the main scale.  It is easy to see how 'balanced' that enclosure is, and therby to estimate the next digit.<BR>--Wikidity (talk) 07:26, 1 March 2012 (UTC)
thread_title:  linear scale, zero point 

message: On the closup picture (with the 2 red markings), you can see that on the vernier scale, the line that matches up exactly, is the ",6" line and not the ",58" one.
So the measurment should be 3,6 mm and not 3,58 mm.
Unless with "closest alignment" is really meant that one that comes the closest, but doesn't line up exactly. (Which is what I learned).
Vernier scales are hard enough to read in real life; the only person who could say with any certainty which mark lined up is the photographer at the time of the photograph.  Parallax error for the win.  - Toastydeath 02:02, 6 September 2006 (UTC)
replies: text: I Have added a note to this effect. This is also noted on the German article. Lumos3 09:23, 28 October 2006 (UTC)

text: A way to avoid parallax would be to place the callipers on a scanner and digitise them like a document (using a tranparency sheet to protect the scanner).128.240.225.9 (talk) 13:32, 27 March 2015 (UTC)

text: It's also misleading because it doesn't read 3.58, it reads 0.358. The (unlabeled) scale appears to be marked in cm, not mm. Yet the label adhered to it is in mm, as is the caption. Maybe it's because I'm American, but this took me a bit to decipher, and I already knew how to use Vernier scales. I may have to take and submit a photo from the scale on my barometer.

message: There is a slight lack of clarity in the following sentence: 
Zero error may arise due to knocks that cause the calibration at the 0.00 mm when the jaws are perfectly closed or just touching each other.
Perhaps it could be altered to: 
Zero error may arise due to knocks that cause the 0.00 mm marks to be misaligned when the jaws are perfectly closed i.e. just touching each other.  — Preceding unsigned comment added by SayWordsToMe (talk • contribs) 01:54, 30 December 2013 (UTC)
thread_title:  Zero error 

message: The article as written is really about calipers, not Vernier scales, and needs to be re-written so the scale is the main topic.
And isn't the Lalande reference a primary source, not a secondary source?
