About Resistance Standards and Decades
Resistance standards and decades provide highly accurate, standard values of resistance for testing, comparing, and calibrating electrical and electronic components and products. Measured in ohms (W), resistance is the degree to which a body opposes the passage of electrical current. Resistance standards usually consist of a single, fixed-value component or several components (e.g., several fixed-value resistors) that are not in the same circuit. Resistance standards with multiple components often have multiple posts or a rotary switch for selecting different resistance values. Decades, decade boxes, or decade substituters are digitally variable and usually consist of multiple components in a single circuit. The standard resistance value is selected by varying the number of resistors in the series or parallel circuit. RTD simulators provide resistance values for the calibration and testing of resistance temperature detectors (RTD) at specified temperatures. Resistance standards and decades that include rheostats or potentiometers are also available.
