100 T-BERD/MTS 5800 Getting Started Manual
The best method of preventing ESD events is to use an
ESD wrist strap and/or use a grounding mat or table.
JDSU recognizes that most field users will not have
access to these items at will and therefore cannot have an
ideal, ESD-free environment.
In this case JDSU offers the steps below to help reduce
the chances of an ESD event as much as possible.
a Zero Potential - Most importantly, make sure that you
and the test set are at Zero Potential by touching the
metal frame of the AC mains power strip before
touching the unit both before and during the test.
b Restricting movement – When achieving zero potential
through the above means is not practical, it is recom-
mended to stand upright while using the test set or
otherwise minimize movement. Even when still, use of
ESD-safe furniture is recommended whenever
possible.
c Clothes - Make sure not to wear any clothing that
builds excessive electrical charge, such as a wool
sweater.
d Weather - Electrical storms can increase the risk of
ESD events. Unless absolutely necessary, try not to
use the test set during an electrical storm.
e Accessories - To help reduce ESD and help prevent
other problems, it is also a good idea to remove all
jewelry.
