static fields built up on other things, like you and your clothing, from discharging

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.
•
Always wear an Anti-ESD wrist strap when working on the electronic
assemblies of your analyzer.
An anti-ESD wrist strap keeps the person wearing it
at or near the same potential as other grounded objects in the work area and allows
static charges to dissipate before they can build to dangerous levels. Anti-ESD wrist
straps terminated with alligator clips are available for use in work areas where there
is no available grounded plug.
Also, anti-ESD wrist straps include a current limiting resistor (usually around one
meg-ohm) that protects you should you accidentally short yourself to the
instrument’s power supply.
