6. TEST RESULT: IMMUNITY
6.1 Electrostatic discharge
RESULT : PASS
6.1.1 Measurement Procedure
The immunity against electrostatic discharge was made accordance with EN55020:2002+A1:
2003.
2003.
The test set-up was made accordance with EN61000-4-2:1995+A1:1998+A2:2001 in
screened room. A ground reference plane was located on the floor, and connected to earth via
a low impedance connection. The return cable of the ESD generator was connected to the
reference plane. In case of table top equipment, EUT was placed on the reference plane on
80cm of insulating support. And a vertical coupling plane (VCP) of 0.5*0.5m was located 10cm
from the EUT’s sides. The VCP was connected to the reference plane via a cable with a 470㏀
(2EA) resistor. The test was made by applying contact and air discharges to the EUT and
contact discharges to the VCP/HCP. When applying the discharges to the VCP the tip of the
generator was located at the middle edge of the VCP. The VCP was located 10cm from each
side of the EUT. Contact discharges of up to ±4kV were applied to various points of the EUT at
conductive surfaces and to the HCP/VCP. Air discharges of up to ±8kV were applied to various
points of the EUT at non-conductive surfaces.
