Special Features:

Primary ac shunt set c/o 7 separate shunt modules, designed to be used with the holt thermal transfer voltmeter model 6b or the fluke model 540b; each shunt is a 4-terminal resistor providing optimum freq response well beyond the audio region; controlled thermal characteristics ensure stable current measurements up to 26 amps; included is rugged formica carrying case for dust-free module storage and transportation

Properties:

A series of fixed precision resistors or bars of metal so positioned that, by means of an integral switching mechanism, any of a number of specific values of resistance can be placed in parallel with a basic direct current instrument to permit determination of current values exceeding the actual range of the instrument itself.
