The answer depends on what aspect of the scale drawing you wish to calculate.
LC= Value of one main scale division Total number of divisions on vernier
Zero error is defined as the condition where a measuring instrument registers a reading when there should not be any reading. In case of Vernier calipers it occurs when a zero on main scale does not coincide with a zero on Vernier scale. Source: calculatored and written by Shaun Murphy
where on the vernier caliper would you read to obtain the vernier scale reading
No unit for vernier scale coincidence. But as we multiply it by least count which has unit then we get vernier scale reading with the same unit. Of course main scale reading and vernier scale reading would have the same unit
1)Main Scale is fixed(It does not move) Vernier scale slides along main scale.2)Least count of Mainscale is 0.1cmLeast count of vernier scale is 0.01cm
Vernier scale consists of main scale and vernier scale. The first line or the zeroth line coinciding with the main scale reading is the main scale reading. The vernier line except zeroth line coinciding with any line on main scale is the main scale reading.
Their Vernier scale consists of two readings; the Vernier scale and the main scale. One can read that by the first line is the main scale and the next line is the Vernier reading.
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
It depends on the graduations on the vernier scale.
0.1 mm
The least count of the vernier can be measured by using the formula stated below. Least count (L.C) = 1 M.S.D - 1 V.S.D Example; vernier scale is constructed by taking 49 main scale divisions dividing them into 50 divisions ie. 49mm divided into 50 parts therfore 1 vsd=49/50 mm=0.98mm 1 MSD=1mm substituting in formula L.C = 1 M.S.D - 1 V.S.D L.C=1-0.98=0.02mm
To obtain the main scale reading on a vernier caliper, you would read the measurement value aligned with the zero mark on the main scale.
It is the scale on a micrometer.
hey ! hi iam gonna tell you how to find the least count of a vernier scale. first of all lc is the least possible measurement made by an apparatus this stand as a symbol of its accuracy now coincide the 0 of main scale to that of vernier scale if n main scale divisions = m verneier scale divisons then 1 vsd = n/m msd then lc = 1msd - 1 vsd (if n>m) = 1 vsd - 1 msd (if n<m)
