Introduction; Required Equipment - Fluke 8845A Calibration Manual

Introduction

This chapter of the Calibration Manual provides performance tests to verify the Meter is
operating within published specifications as well as a complete calibration procedure.
The performance test and, if necessary, the calibration procedure can be performed both
periodically and after service or repair.
The performance tests can be used as an acceptance test upon receipt of the Meter. Use
the 90-day specifications when performing an acceptance test after performing a
calibration.
