Tests and Adjustments

N5230A

Non-ANSI/NCSL Z540–1–1994 Verification

For non-ANSI/NCSL Z540-1-1994, perform the preliminary checks and the performance
tests while

stopping to troubleshoot.

Refer to

Figure 3-2

for test flow. Troubleshoot and

repair the first problem encountered without continuing to other tests. After you
troubleshoot, repair, and adjust, repeat the

last failed

portion and generate a new set of

data.
