Calibration with Data

If you’re not concerned about the extra value offered by an accredited cal, Keithley Calibration with Data, available on most products, includes a calibration certificate and measurement report indicating "before" (as found) and "after" (as left) data. All measurements are traceable to the appropriate national and international standards organizations. Most of these calibrations are performed in compliance with calibration standard ANSI/NCSL Z540-1. (Please note that before data is not typically available on products in need of repair.)
