Fluke 5522A — ±1020 V / 20.5 A Multi-Product Calibrator, 11 ppm Best DCV Accuracy Multi Function Calibrator
The Fluke 5522A covers a broad workload for mobile or bench calibration, sourcing precision DC/AC volts to 1020 V, current to 20.5 A, resistance to 1.1 GΩ, and capacitance to 110 mF. Best DCV performance reaches 11 ppm (1-year), while ACV provides 0.019%-class uncertainty at 100 V, 45 Hz–1 kHz, with extended-band sine capability to 2 MHz for special tests. Dual outputs support power, phase (0.01° resolution) and harmonics, and robust reverse-power protection improves survivability. Standard GPIB/RS-232 and a 10 MHz reference ease automation and system tie-in; oscilloscope options extend coverage to 600 MHz/1.1 GHz, and the 52120A amplifier enables high-current clamp workloads. Calibration documentation is available on request.
