A screw gauge with a pitch of 0.5 mm and a circular scale with 50 divisions is used to measure the thickness of a thin sheet of Aluminium. , Now, when the screw gauge is closed, look at the reading. a) If the zero of the circular scale is in line with the main scale, zero error = 0 b) If the zero ofthe circular scale is above the zero of the main scale, zero error = negative (eg: – 7 divisions).
Jul 26, 2008 · First you read the compass. Then you find the correction for the heading closest to the heading the compass reads, interpolating if needed. Then you add the correction to the heading to get the ...
Dec 04, 2019 · For a screw gauge of 100 circular division, the pitch is 1 mm. Least count of screw gauge. A screw gauge of 100 divisions will move the cap scale along the main scale by 1/100 of mm-0.01 mm. This is the minimum value up to which a screw gauge can measure and is known as its least count.
