A digital meter is used to determine the torque of a rotating shaft using single toothed flanges and inductive pick-ups. Static calibration show that the flange twist by an angle of one degree for an applied torque of 1000 Nm. In a test with the shaft rotating at 500 r.p.m., the torque calculated from the timer readings is 1200 Nm. What is the maximum possible error of final digit on the timer display represents units of 10^-5 se and accuracy of instrument specified 0.05% of the reading ± 1 in the final digit?
