▶ Description
The 1433 Decade Resistors are primarily intended for precision measurement applications where their excellent accuracy, stability, and low zero resistance are important. They are convenient resistance standards for checking the accuracy of resistance-measuring devices and are used as components in dc and audio-frequency impedance bridges. Many of the models can be used up into the radio-frequency range.
IET continues to produce the 1433 Series Decade Resistors to the same exacting specs as GenRad.
The individual decades (0510 Decade-Resistance Units) are available for applications requiring only one decade or as components to be built into experimental equipment, production test equipment, or commercial instruments.
The 1433 Decade Resistor is an assembly of 0510 Decade-Resistance Units in a single cabinet. Mechanical as well as electrical shielding of the units and switch contacts is provided by the attractive aluminum cabinet and panel. The resistance elements have no electrical connection to the cabinet and panel, for which a separate shield terminal is provided.
Each Type 0510 Decade-Resistance Unit is enclosed in an aluminum shield, and a knob and etched-metal dial plate are supplied. Each decade has ten resistors in series; the contacts in the lower-valued decades have a silver overlay to ensure stability of resistance, and all the decades have a silver-alloy contact on the zero setting to give low and consistent zero resistance. The resistors used in construction minimize the effects of residual reactance.

Accuracy (the difference between resistance setting and the value at “zero setting”) at 23°C; traceable to SI:
≤1 MΩ steps: ±(0.01% + 2 mΩ) 10 MΩ steps: ±0.03%
Zero Resistance:
≤1 MΩ decades: <1 mΩ per decade at dc 10 MΩ decade: ≈3 mΩ at dc
