An additive curcuit was introduced in order to solve the problem of the common deviation in force and weighing system composed of resistance strain sensor. According to error theory tool, legal design standard and approximation theory optimization method, the formula of deviation resistance R_G, adjustable potential device R_W and control resistance and the rejection standard of functional results were obtained.
