Abstract
A device for measuring small units of force or weight, such as the tracking force of a phonograph cartridge, includes an elastic flexure member having an electric contact for engagement with an encoder. As the flexure member is deflected by an amount proportional to the force being measured, contacts on the encoder are sequentially activated to provide an electric signal used to drive on analog, digital or numeric visual display or readout of the measured force. The device of the invention may also include a mechanism for providing a second point of support for the flexure member and a second visual scale to provide a greater range of measurement.
