4.1 General
4.1.1 Introduction
The following information, provides the complete Calibration Adjustment procedure for
the Fluke 433/434/435 Power Quality Analyzer (referred to as Analyzer). The Analyzer
allows closed-case calibration using known reference sources. It measures the reference
signals, calculates the correction factors, and stores the correction factors in RAM. After
completing the calibration, the correction factors can be stored in FlashROM.
The Analyzer should be calibrated after repair, or if it fails the performance test. The
Analyzer has a normal calibration cycle of one year.
4.1.2 Calibration number and date
When storing valid calibration data in FlashROM after performing the calibration
adjustment procedure, the calibration date is set to the actual Analyzer date, and
calibration number is raised by one. To display the calibration date and - number:
1. Press
