2752 PRECISION DOUBLE BRIDGE
The resistance elements are made of selected manganin wire, stabilized by both artificial and natural aging after being wound.
The dial switches offer low contact resistance and little change due to aging, giving stable operation. Inner/outer contact type plugs are used for changing the multiplication factor, assuring little change in the resistance due to reinsertion of plugs.
