THUMB WHEEL DECADE RESISTANCE BOX
Thumb Wheel Resistance Box Type 7400-A is a resistance standard substitution instrument. It can be used as a source of resistance of a known accuracy of the order of + 1%. A known value of resistance (ranging from 1 ohm to 1 Meg ohm) can be drawn from the instrument and can be substituted in an electrical circuit or can be used for resistance simulation.
