Replacing a Part
Introduction
Introduction
To order parts contact your local Agilent Technologies Sales and Service office.
Assembly Replacements
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”.
