How It Is Used
Each dial sets one decade of the total, and the resistance in circuit is read directly from the dial positions. This decade resistance box for the lab is used as the variable known arm in bridge measurements, to model circuit loads, or to stand in for a sensor whose resistance changes.
Frequently Asked Questions
How is a value set on the 7 Decade Resistance Box?
Each of the seven rotary dials sets one decade, and the total resistance is the sum of the dial settings.
