Abstract
PURPOSE:To set an optional test speed with analog sensation and improve the operability by providing a knob, a rotary encoder, a decoder, etc., and enabling the optional test speed to be set. CONSTITUTION:As the know 10 is displaced, a decoder 12 outputs an up-pulse signal or down-pulse signal corresponding to the displacement position according to a phase signal outputted by the rotary encoder 11. Then a binary code signal is outputted by counting the pulses of the up- or down-pulse signal and a microcomputer MC computes a speed setting signal matching with the binary code signal. Namely, the knob 10 is rotated so as to a desired test speed to be set over a look at a test speed displayed on a display 15, and fixed at a desired place. In this state, a motor 6 is driven to accurately test characteristics of various materials while setting the desired test speed artificially and freely by the continuous displacement.
