Fluke 5520A Multi Function Calibrator 20A Direct Current Output with Pressure Measurement 600 MHz Scope Calibration

Fluke 5520A High Performance Multi-Product Calibrator

The Fluke 5520A Multi-Product Calibrator builds on the industry-standard 5500A platform, extending workload coverage with improved accuracy, expanded measurement ranges, and advanced calibration features designed for metrology professionals and calibration laboratories.

Key Differentiators

20A Direct Current Output

Unlike the standard 11A limit on most multi-product calibrators, the 5520A delivers DC and AC current up to 20.5A, enabling direct calibration of high-current meters, current clamps (up to 1000A with the 5500A/COIL 50-Turn Coil accessory), and power instruments without external amplifiers. This expanded range covers 5½ and 6½ digit multimeters with better than 4:1 Test Uncertainty Ratio (TUR).

Pressure Measurement with Fluke 700 Series Modules

The 5520A uniquely supports 27 Fluke 700 Series Pressure Modules, covering ranges from 0-10 inH₂O (0-2.5 kPa) to 0-10,000 PSI (0-70,000 kPa). This integrated capability eliminates the need for a separate pressure calibrator, allowing you to calibrate pressure transducers, gauges, and transmitters alongside your electrical workload with a single instrument.

Comprehensive Calibration Coverage

The 5520A calibrates the widest range of electronic test tools with a single instrument:

• Handheld and Bench Multimeters — up to 6½ digits, analog and digital
• Oscilloscopes — 300 MHz, 600 MHz, or 1.1 GHz with optional SC1100
• Thermocouple and RTD Thermometers — 12 thermocouple types, multiple RTD curves
• Process Calibrators — DC voltage, current, and resistance
• Power Meters and Power Quality Instruments — with optional 5520A-PQ
• Current Clamps and Clamp Meters — direct and with 50-Turn Coil
• Data Loggers, Strip Chart Recorders, and Panel Meters
• Pressure Gauges and Transducers — via Fluke 700 Series Modules
• Three-Phase Power Meters — with Phase Lock capability
