Fluke 5520A — 1020 V / 20 A Multi-Product Calibrator Multi Function Calibrator

The pre-owned Fluke 5520A combines precision sources for voltage, current and resistance in a single chassis that reaches ±1020 V, ±20 A and 100 MΩ. With typical 11 ppm DC accuracy and wide-band AC outputs to 500 kHz, it delivers a 4∶1 test-uncertainty ratio when calibrating 6½-digit bench meters, handheld DMMs, clamp meters (via external current booster) and power analyzers. Programmable harmonics, phase control and built-in MET/CAL® procedures slash setup time, while GPIB/RS-232 connectivity lets the calibrator drop straight into automated systems. Supplied fully tested, freshly calibrated and firmware-current, each unit provides traceable Fluke performance and immediate cost savings compared with new equipment.
