least count Mechanical Measuring
The least count of dumpy level depends on the readings on staff. Generally we use 5 mm least count staff, so the least count of the dumpy level is 5mm. The least count of theodolite is 20(20 seconds). It can be observed in vernier scale of theodolite instrument.... Define least count and mention the least count of a mechanical comparator. Least count - The least value that can be measured by using any measuring instrument is known as least count.

14/09/2007 · The Least Count is the discrimination of a vernier instrument. All measuring instruments used in the subject of physics can be used to measure various types of objects, but all do so without considering the detail of accuracy.
- All parts of the vernier caliper are made of good quality steel and the measuring faces hardened to 650 H.V. min. Application :- Internal as well as external linear dimensions for a length as less than 200mm. with an accuracy up to ± ( 90+0.021)µm. Least count :- Let us consider vernier scale reading =50 division. This division consider with exactly 49 th on the main scale. So one vernier
