11.3 Test set-up 
 
<Floor standing>The EUT was placed on a non-metallic support 0,1m above a reference ground plane 
(RGP) and was put into operation according to the specified operating mode. 
 
<Table top>A horizontal coupling plane (HCP) was placed on a 0.8m high non-metallic table above a 
2.6m by 1.8m reference ground plane (RGP) and connected to it through a cable with two 470k
Ω 
resistors at each end. The EUT was placed on an insulation sheet on the HCP and was put into operation 
according to the specified operating mode. 
 
A vertical coupling plane (VCP) was connected to the RGP through a cable with two 470k
Ω resistors at 
each end. 
 
   
11.4 Test conditions 
 
Test level:                                            4kV Contact discharge 
                                                             8kV Air discharge 
 
Number of discharges 
at each point:                                       10 of each polarity 
 
Performance criterion:                         B 
 
ETU position:                                       Table top standing 
 
Indirect contact discharges were applied to the VCP and the HCP The selected test points of the EUT are 
listed in this table..
