How do you read a vernier inch scale?
A Vernier Caliper To read a vernier caliper: Read the large number division first. Read the small number division. Read the number of smaller subdivisions. Each represents 0.025 inches to be added to the measurement. Read which line on the vernier lines up with a line on the main beam. Click to see full answer….

Considering this, how does a vernier scale work?The vernier scale works on the principle of using alignment of line segments displaced by a small amount to make fine measurements. Human eye can easily detect this alignment of lines which is the main fact that drives a vernier. A vernier scale has a main scale and a vernier scale.Furthermore, what is a zero error? AQA Science: Glossary – Zero Errors Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, e.g. the needle on an ammeter failing to return to zero when no current flows. A zero error may result in a systematic uncertainty. Hereof, what is the unit of vernier scale? 1, the smallest measurement on the main scale is 0.1 cm or 1 mm. The vernier scale can read to 0.05 mm. So using both scales, the width can be read to the nearest 0.005 cm (or 0.05 mm).What is main scale reading?The main scale on a Vernier caliper typically tells you the whole number plus the first decimal. Read this just as you would a ruler, measuring to the zero mark on the sliding (Vernier) scale. For example, if the 0 on the sliding scale lines up with the 2 inch mark, your measurement is 2 inches.
