Introduction; Required Equipment - Tektronix DMM4020 Technical Reference 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. A one-year calibration interval is recommended to
maintain the accuracy of the Meter.
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.
