Key Features
Seven rotary decade dials
Decade steps of 1 ohm, 10 ohm, 100 ohm, 1 kohm, 10 kohm, 100 kohm and 1 Mohm
A decade box lets students dial an exact resistance instead of plugging in coils, which makes it quick to balance a bridge or substitute a known value for an unknown one. It is used in bridge circuits, for calibrating meters and circuits, and for matching load resistance in electronics work.
