Abstract
A system is presented with which a computer can be used to provide electronic feedback nulling of a Wheatstone bridge measurement system used for data acquisition. This system provides compensation for drifts away from null resulting from the measurement setup or amplifier drifts with time or temperature. An example of the system in the case of a strain gauge bridge used with a cantilever beam is described
