In a first step, the tests consisted of finding an experimental
configuration in which the strikes are observed, almost
alternately on one or the other of the two ESEAT positioned
under the metal plate. The first 30 shocks were used to
determine the U50 voltage through the "up and down" method.
The following 30 shocks are done for a voltage slightly above
this value. Two ESEAT (PIX3-60) are tested and they are
previously shorted to make them inactive
