Decade Resistors

Decade resistors are precision resistance reference instruments that provide selectable, known resistance values in fixed steps for calibration and verification tasks. They are significant because they offer stable and repeatable resistance settings across a wide range, supporting traceable and consistent resistance measurements without changing individual standards.

Key applications include calibration of digital multimeters and ohmmeters, verification of electrical calibrators and resistance bridges, RTD and sensor simulation, and laboratory training or troubleshooting. Decade resistors are widely used as working standards in calibration labs, electronics manufacturing, and industrial test environments. ATEC offers decade resistors from manufacturers including Fluke Calibration, AMETEK, and Additel.
