About Decade Boxes
A decade box is used when you introduce a variable resistance into a circuit to check the value of another resistor. In this case, the value you are studying is the resistance value supplied by your resistance and continuity meter or multi-meter.
The decade resistor box contains a variable set of resistors, some in kilo ohms and some in mega ohms, which can be dialled in through interface buttons on the unit's housing. The selected resistance value is then used to check that your meter readings are a true reflection of insulation or continuity in an electrical circuit. The resistors are available for use in the box increase by multiples of ten which is why it is called a decade box.
