PRODUCT SPECS

(From Used-Line T&M Specifications )
Status Discontinued

The Genrad Type 1432 Decade Resistor is an assembly of Type 510 Decade-Resistance Units in a single cabinet. Mechanical and electrical shielding of the units is provided by the rugged aluminum cabinet and panel, which completely enclose both the resistance units and switch contacts. The resistance elements have no electrical connection to the cabinet and panel, for which a separate shield is provided.

The decades are built in three-dial, four-dial, and five-dial assemblies. Each decade has eleven contact studs and ten resistance units, so that the dial values overlap. Positive detent mechanisms in conjunction with bar-type knobs permit the operator to sense the position of the switches without looking at the panel.

Winding methods are chosen to reduce the effects of residual reactances. The 1Ω, 10Ω, and 100Ω steps use winding techniques that minimize inductance. The 0.01Ω and 0.1Ω steps are straight wire and hairpin-shaped ribbon respectively, and the high valued units are straight wound on mica forms.

  • Low zero resistance: <0.003Ω per decade
  • High accuracy: 0.05% for most decades
  • Low temperature coefficient of resistance
  • Negligible thermal emf to copper
  • Resistors are adjusted to specified values at their own terminals rather than at the box terminals, so that resistance increments are always correctly indicated
  • Residual impedances are small and are given in the specifications so that approximate frequency characteristics can be computed
  • Maximum current for each decade based on 40° C temperature rise is engraved on panel
