5520A Multi-Product Calibrator

The Fluke 5520A is a high performance multi product calibrator that builds on the 5500A’s capabilities, extending its workload coverage even further. Its improved accuracy, expanded ranges, and capability to calibrate 5 1/2 and 6 1/2 digit multimeters. In terms of specifications, the Fluke 5520A calibrator offers DC and AC volts to 1000 V, DC and AC current to 20 A, outputs four different waveforms (sine, square, triangle, and truncated sine), resistance to 1100 Mohm, capacitance to 110 mF, simulated power to 20.5 kW with phase control, simulate and measure nine different thermocouple types, simulate RTDs.
Here are the key features and functions of the Fluke 5520A:
Lower output uncertainties to meet the requirements of 51/2 and 61/2 digit multimeters
Phase lock to simplify simulation of three-phase power. You may also sum the current from multiple 5520As to perform high current tests, such as direct calibration of current clamps or verification of current transformers.
Current output expanded to 20A. Verify current clamps to 1000A using the 5500A/COIL 50-Turn Coil accessory
Pressure measurement using any of the 27 Fluke 700 Series Pressure Modules, which cover ranges from 0-10 (0-2.5 kPa) H2O to 0-10,000 PSI (0-70,000 kPa) to calibrate pressure gauges, transducers and other indicators
Temperature measurement, making it easy to record environmental conditions present at the time of calibration, as required by all quality standards
Improved phase and frequency accuracy and the capability to reference the 5520A to an external 10 MHz frequency standard to support calibrating frequency counters
Wider capacitance calibration and resistance ranges
Increased compliance voltage in current output modes
Expanded ac Volt
*Hertz capacity to 330V at 100 kHz
