The Fluke 5720A is a multifunction precision calibrator designed to address the most demanding electrical calibration workload. Serving as a world-class calibration standard, it sources direct and alternating voltage, current, and resistance with uncertainty specifications engineered to support the calibration of high-accuracy digital multimeters up to 8.5 digits. The system features innovative Artifact Calibration to simplify maintenance and support, requiring only three external standards to align all ranges and functions. Its performance can be expanded with the optional 5725A boost amplifier.
