Abstract

Abstract: The present paper deals with the theory of resistance trim by means of source wheatstone bridge in the laser resistance trim system and presents the method of removing line resistance and junction resistance in low resistance measurement. High precision programmable power circuit of the laser resistance trim system is analyzed in time-domain, and the conclusion of removing line resistance and junction resistance is achieved.

Key words: lasers, resistance, wheatstone bridge, measurements
