Main purpose
This instrument can be used to measure the unit resistance of yarns made by blending or compounding conductive fibers with other fibers. The yarns are connected in parallel as equal resistance resistors, and the resistance value of the parallel resistors is measured to calculate the unit resistance of the yarns, which is used to represent the conductivity of the yarns.
