1.3.4 Remove the load and check that the reading now returns to zero.
1.3.5 The full range calibration can be carried out by putting the available weights of 500 g, 1
kg and 2 kg incrementally while the reading of torque of each increment should be recorded. The
obtained values should be within the tolerance of ± 0.5 Nm of the calculated values.
1.3.6 Plot the graph of the torque reading against the applied torque (0.5 x load x 9.81),
giving a linear relationship. Calculate the slope which should be approximately unity.
