Precision Decade Resistor GenRad 1433 Series Page 1 of 2 The 1433 Decade Resistors are convenient resistance standards for checking the accuracy of resistance-measuring devices. They are pri- marily intended for precision-measurement applica ons where accuracy, stability, and low-zero-resistance are important. They are used as components in dc and audio frequen- cy impedance bridges.
