Precision quality resistance box consist of 12mm approx.1/2 thick rectangular brass block, non inductive, double covered Eureka Constantan wire is wound on bakelite spool,enclosed in a teak wood box. Accuracy 0.1. Construction Details In plug type resistance box the contact between plug and socket is the most important feature affecting reproducibility of results. Use tapered brass plug and split block. Although expensive to make, this is the best form of contact. It requires accurate machining to ensure interchangeability i.e. plugs and lugs are cut to a fine taper and are interchangeable. The plug headsare machine moulded, are of heavy insulated bakelite in a beautiful shape. Selected double cover Eureka or Manganin wire is wound on the bakelite spool. Sufficient heat treatment is processed through to avoid any appreciable shifting of values. The coils are mounted on the lower side to an insulating panel with the help of threaded brass leads...
