An ordinary decade resistance is made of ten resistive elements for obtaining ten resistance values with a constant step. A resistance box is composed of more than one decade. In this paper, a new design for a decade resistance formed by four resistive elements is introduced. This decade is manufactured to be controlled by using a micro-controller technique as demonstrated in this research. Its ten resistance steps can be obtained by manual control through a designed assembly language program with push-button switches or by automatic control through a designed LabView® program and a computer serial port. All of the control signals are transmitted to the four resistors by the corresponding four electronic relays. The ten-output values of the resistance steps of this new decade resistance are accurately calibrated through this investigation. Analysis of the measurement results is carefully performed including the uncertainty calculations to validate this new fabricated decade resistance.
