The IET Labs RCS-500 is a dual-function decade box providing resistance and capacitance substitution in a single, lightweight unit. Engineered for calibration, testing, measurement, design, and troubleshooting across laboratory, field, and automated testing environments, it combines seven decades of resistance control with six decades of capacitance in a compact, shielded enclosure. Direct-reading thumbwheel switches with color-coded ranges minimize operator error and reduce bench clutter.
