Electrostatic
discharge (ESD)
IEC 61000-4-2 ± 6 kV contact
± 8 kV air Test level Contact ± 6 kV
Air ± 8 kV Floor should be wood, concrete
or ceramic tiles. If floor is
covered with synthetic material,
the relative humidity should be
at least 30%.
Electrical fast

lines
Contact ± 6 kV
Air ± 8 kV
± 2 kV for power

± 1 kV for
input/output lines
Power ± 2 kV
Signal ± 1 kV Mains power quality should be
that of a typical commercial or
hospital environment.

IEC 61000-4-11 < 5% UT (> 95% of
dip in UT for 1/2
cycle)
40% UT (60% of dip
in UT) for 5 cycle
70% UT (30% of dip
in UT) for 25 cycle
< 5% UT (> 95% of
dip in UT) for 5 sec < 5% UT (> 95% of
dip in UT) for 1/2

in UT) for 5 cycle
70% UT (30% of dip
in UT) for 25 cycle
< 5% UT (> 95% of
dip in UT) for 5 sec Mains power quality should be
that of a typical commercial or
hospital environment. If a better
mains power quality is required,
it is recommended that the
Atomlab 500 is powered from
an uninterruptible power
supply.
Power
frequency
(50/60 Hz)
magnetic field
IEC 61000-4-8 3 A/m 3 A/m If image distortion occurs, it
may be necessary to position
the Atomlab 500 display further
from sources of power
frequency magnetic fields or to
install magnetic shielding. The
power frequency magnetic field
should be measured in the
intended installation location to
assure that it is sufficiently low.
Conducted RF
IEC 61000-4-6 3 Vrms,
150 KHz to 80 MHz 3 Vrms,
150 KHz to 80 MHz
Radiated RF
IEC 61000-4-3 3 V/m,
80 KHz to 2.5 GHz 3 V/m,
80 KHz to 2.5 GHz Portable and mobile RF
communications equipment
should be used no closer to any
part of the Atomlab 500,
including cables, than the
recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
