Environment:
The 1433 Decade Resistors are convenient
resistance standards for checking the accuracy of
resistance-measuring devices. They are primarily
intended for precision-measurement applications
where accuracy, stability, and low-zero-resistance
are important. They are used as components in dc
and audio frequency impedance bridges.
