5.1.1 Introduction

The following information, provides the complete Calibration Adjustment procedure for
the Fluke 190-104 (100 MHz) / 190-204 (200 MHz) ScopeMeter Test Tool (referred to as
Test Tool). The Test Tool 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 Test Tool should be calibrated after repair, or if it fails the performance test. The
Test Tool has a normal calibration cycle of one year.

5.1.2 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 Test Tool date, and
calibration number is raised by one. To display the calibration date and - number:
