Fluke 5502A Multi-Product Calibrator

The Fluke 5502A Multi-Product Calibrator is a multifunction source and measurement instrument for calibrating electrical test equipment across calibration laboratories and service centers. It generates DC and AC voltage, current, resistance, and capacitance, while simultaneously sourcing voltage and current to simulate DC and AC power conditions. The unit sources thermocouple and RTD temperature signals, supports optional oscilloscope calibration to 600 MHz, and extends current capability through external amplifiers and coils.

RS-232 and IEEE-488 interfaces enable remote control and integration with MET/CAL® Plus Calibration Management Software for automated workflows.
