Excellent long-term stability: The resistance elements are made of selected manganin wire, stabilized by both artificial and natural aging after being wound.
Perfect guard system
Stable measurement: 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.
