Answer» Answer: (i) calculate L.C. =pitch NUMBER of division on circular scale (ii) P.S.R = NTH division × pitch (III) Observed reading =P.S.R +(H.S.R×L.C.) (iv) Zero error =[H.S.R. + (N -n) ×L.C.] (v) CORRECTIONS is positive if error is negative (vi) Correct measurement = observed reading + correction. (vii) Correct measurement =7.25 mm |
