Abstract
A electro-mechanical device for measuring the angle made by two rotatably joined members comprising a pair of rotatably connected elongated arms and electrical circuit means mounted on one of the arms and associated with the rotatable pin connector of the arms. The circuit, powered by a battery, encodes the angle of the pin preferably via a potentiometer and transmits the information to a decoding device, preferably a voltmeter, and then to a digital display device also mounted on one of the arms.
