Info The "0,07" is read directly in the vernier (which is graduated in 1/100 cm), at the exact point where there is a coincidence between a segment of the vernier scale and a segment of the main scale (i.e., when they line up). But this is the kind of explanation that we should put in the caption, not in the picture itself.
Vernier caliper scales; main at top, vernier at bottom. It reads 3.58 ± 0.02 mm by adding 3.00 mm (left red mark) on the fixed main scale to vernier 0.58 mm (right red mark). The main scale reading is that to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales.
This would be a simply calibrated caliper, but the addition of a vernier scale allows more accurate interpolation and is the universal practice; this is the vernier caliper. Vernier, dial, and digital calipers can measure internal dimensions (using the uppermost jaws in the picture at right), external dimensions using the pictured lower jaws ...
The main scale reading is the rightmost graduation that is to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales. The 0.02 mm engraving indicates the caliper's accuracy and is the "Vernier constant" for this scale. He was born in Ornans, France, in 1580. He was ...
I've read every section in this several times, and I still can't grasp how it works. Okay, so you read the big measurement off of the big scale, and the finer one of the vernier scale. But how does the vernier scale know where to indicate? The animation shows a caliper measuring a bolt's width; when it closes, the scale is at 2.4.

A possible heading for dial, digital, and vernier: "Slide calipers". That's the heading Starrett uses for that category , which also includes non-vernier direct reading calipers--like a vernier but with just one mark on the stationary part. Ideas for the other category title:
Budget carrier Spirit Airlines filed for bankruptcy this week, stoking concern about how the financial peril of a low-fare option could impact prices across the industry. The Florida-based company ...
