Table 16-1 lists the adjustments and performance verification tests needed
after an assembly replacement.
After an assembly is replaced, find the assembly that has been replaced in the
left-hand column, and then perform the recommended adjustment and/or
performance verification test. Making the recommended adjustments and/or
performance verification tests doesn’t guarantee all published specifications
are being met. Only a full instrument calibration will do this.
The following procedures are also included in the “Additional Tasks” on
page 476.
— “Calibration Data Backup and Restore”
— “BIOS Settings Verification”
— “Operating System Initialization”
— “FPGA Synchronization”
— “Programming Model and Serial Numbers”
Refer to the analyzer user’s guide for information on instrument warm-up
before performing any of the procedures listed in this chapter.
