Decade Resistance Box Hookup Guide
Introduction
A decade box is a tool that contains resistors of many values accessed via
mechanical switches. Adjust the knobs to output any of the discrete
resistances offered by the box.
They are known as
decade
boxes because they have controls that
correspond to the digits in a decimal number - a control for the ones
position, a control for the tens position, a control for the hundreds position,
and so on.
Traditional decade boxes looked like something out of Dr. Frankenstein’s
lab - large wooden enclosures, with engraved front panels and big Bakelite
knobs. They were available in three main types - resistance, capacitance
