Before You Begin
Before checking, verifying, or adjusting the analyzer, refer to the following
paragraphs to:
— Make sure the operating environment is within 19 to 27 C and 5 to 95%
— Make sure that proper electrostatic discharge (ESD) protection is provided.

— Review the principles of connector care.

Protect Against Electrostatic Discharge (ESD)
This is important. If not properly protected against, electrostatic discharge can
seriously damage your analyzer, resulting in costly repair.
To reduce the chance of electrostatic discharge, follow all of the
recommendations outlined in "Electrostatic Discharge Protection" on
page 1-5, for all of the procedures in this chapter.
