ABSTRACT:
A first pulse is electromechanically generated for each rotation of a body and a predetermined number of second pulses are also electromechanically generated for each rotation. The first pulse is applied as an input binary digit to a shift register having storage elements equal in number to the second pulses generated for each rotation. The second pulses are applied as a clock input to the shift register to cause shifting of the binary digit through the storage elements in a step along manner. A plurality of monostable multivibrators are coupled to respective ones of the storage elements to receive the stored content in each storage element. Each of the multivibrators is provided with a manually adjustable time constant value. Adjustment is made of each time constant value to compensate for any possible error in spacing between successive ones of the second pulses due to mechanical tolerances in the manufacture of the electromechanical pulse generating mechanism.
