Assembly Replacements

Replacing a Part

Introduction

To order parts contact your local Agilent Technologies Sales and Service ofﬁce.

For most parts, you can either order a new assembly or an exchange assembly. Exchange assemblies are factory-repaired, inspected, and tested. If you order an exchange assembly you must return the defective assembly for credit.

With some assemblies you will receive a Memory Card that contains factory-generated calibration data for the assembly. There will also be an instruction sheet for loading the calibration data into the instrument after you replace the defective assembly. With exchange assemblies, you must return the Memory Card with the defective assembly to receive full credit.

Adjustments after Replacing Assemblies

The following table shows which adjustments should be performed after replacing assemblies. The adjustments and calibrations are described in chapter 8, “Assembly/ Disassembly”.
