3-1. Introduction
You should recalibrate at the end of either a 90-day or 1-year calibration interval. If you
recalibrate every 90 days, use the 90-day specifications, which provide higher
performance. Use the Verification procedure or any part thereof any time you need to
verify that the Calibrator is meeting its specifications.
Fluke recommends that you return the 5520A to Fluke for calibration and verification.
The Fluke Service Center uses a software-controlled verification process and provides a
detailed test report including traceability to national standards. If you plan to calibrate or
verify the 5520A at your site, use this chapter as a guide. The procedures in this chapter
are manual versions of the software-controlled process used at the Fluke Service Center.
3-2. Equipment Required for Calibration and Verification
The equipment listed in Table 3-1 is required to calibrate and verify performance of the
5520A. If a specified instrument is not available, you can substitute an instrument that
has the same, or better performance.
