PURPOSE:To hold values of torsional torque at specific angle intervals and displaying them digitally by inputting an output signal of an angle of torsional return rotation to a counter, comparing the output of the counter with the input of a setting circuit by a comparing circuit, and inputting the output of the comparing circuit to a digital display device. CONSTITUTION:Angles for resetting the output signal (b) of a torque sensor 7 and an angle signal for holding it are inputted to setting circuits A1, A2.... The counter 20 is cleared with the signal d0 of a start switch S to put a peak holding circuit 13 in a peak hold state. When a sample is twisted back, the torque sensor 7 generates an output signal (b) corresponding to torque Q and a rotational angle detector 3 generates a signal (e) corresponding to an angle theta of torsional return rotation. The signal (e) is inputted to the counter 20, whose output is compared with set angles of the setting circuits A1, A2... by comparing circuits C1, C2...; and only necessary twist angles are held and displayed on a display device 15. |
