Giuseppe,
The resistors, which total approximately 1 megohm, are for operator safety.
Paragraph 5 of section 7.2, "Test set-up for post-installation tests" states
that the resistors are located at each end of the cable "to prevent a
build-up of charge".

Subject: ESD EN 61000-4-2 question
During a quality inspection in my lab the inspector
I've got a non-conformity due to the lack of resistivity check on
the
470 Kohm resistor employed to connect the reference plane of the ESD
table
to the ground.
This is required according to EN 61000-4-2
Could anyone give me some hints in order to understand the influence
of that
resistor on the ESD test ?
Of course I need to reply to the inspector in a formal way
(they usual do not accept answer based on reasonable assumption,
the standard answer i get is: please give me written evidence of
what you
are saying.........)
Thank to all
Giuseppe Rossi
