-1 Multi Function Calibrator
The pre-owned Fluke 5720A elevates multifunction calibration by pairing 7-ppm DC accuracy with 1100 V, 2.2 A and 1 MHz AC capability—plus a 30 MHz wide-band option for RF voltmeters. Direct sourcing of volts, amps and ohms lets one box certify handhelds, 6½-digit bench meters, clamp meters (with the 5725A booster) and oscilloscopes, preserving a ≥ 4:1 test-uncertainty ratio without external standards. Built-in MET/CAL® procedures, colour touchscreen and USB/LAN/GPIB interfaces accelerate automated workflows, while internal diagnostics and self-cal routines reduce downtime. Delivered fully tested, freshly calibrated and firmware-current, each unit ships from stock—offering immediate, audit-ready precision at a fraction of new-instrument cost, all backed by Fluke’s long-term serviceability.
