As long as my analyzer is properly installed, it is safe from damage

caused by static discharges: It is true that when properly installed the
chassis ground of your analyzer is tied to earth ground and its electronic
components are prevented from building static electric charges themselves.
This does not prevent discharges from static fields built up on other things,
like you and your clothing, from discharging through the instrument and
damaging it.

14.4. BASIC PRINCIPLES OF STATIC CONTROL

It is impossible to stop the creation of instantaneous static electric charges. It is not,
however difficult to prevent those charges from building to dangerous levels or prevent
damage due to electro-static discharge from occurring.

14.4.1. GENERAL RULES

Only handle or work on all electronic assemblies at a properly set up ESD station.
Setting up an ESD safe workstation need not be complicated. A protective mat properly
tied to ground and a wrist strap are all that is needed to create a basic anti-ESD
workstation.

For technicians that work in the field, special lightweight and portable anti-ESD kits are
available from most suppliers of ESD protection gear. These include everything needed
to create a temporary anti-ESD work area anywhere.
