The pitch of a screw gauge is 0.5 mm and three are 100 divisions on the circular scale. When the plane
face of the screw is in contact with the plane face of the stud on the frame, the zero of the circular scale is
below the pitch line by 6 divisions. The zero error of the screw gauge is

Answer:
zero error = pitch /Total ddivision ×2CSD
zero error = pitch /Total ddivision ×2CSD = 0.5 /100×2 = 0.01 mm
zero error = pitch /Total ddivision ×2CSD = 0.5 /100×2 = 0.01 mm
zero error = pitch /Total ddivision ×2CSD = 0.5 /100×2 = 0.01 mm
zero error = pitch /Total ddivision ×2CSD = 0.5 /100×2 = 0.01 mm
zero error = pitch /Total ddivision ×2CSD = 0.5 /100×2 = 0.01 mm Reading Calculation-
zero error = pitch /Total ddivision ×2CSD = 0.5 /100×2 = 0.01 mm Reading Calculation- linear scale Reading (LSR)=8× Pitch =4 mm .
