= chord of 60' from the scale / ,--, 1. The measurement increment is too small. Natural Errors These are caused due to variations in nature i.e., variations in wind, temperature, humidity, refraction, gravity and magnetic field of the earth. The probable error, r, using the above equation is given by: r/f = ((f/R)2(r12/f2) + (f/C)2 (r22/f2)) ; f/R = 1/(2C(2N)R2) ; f/C = 1/(2R(2N)C2), r/f = ((0.9/103)2 + (1014/109)2) = 9.001104.
