The 5700A/EP is an upgrade service that extends both the performance and service life of your existing 5700A Multifunction Calibrator. Through the installation of new hardware and software, your working 5700A, no matter how old, will be brought up to the performance equivalent of a state-of-the-art 5720A, at half of the cost of a new calibrator. All work is performed at Fluke's manufacturing facility in Everett, Washington, USA, with rigorous testing and verification performed on the actual 5720A production line.
