is the a.c. mains power supply prior to application of the
test level.
Immunity test

test level
Compliance level Guidance
Electrostatic
discharge (ESD)
IEC 61000-4-2
Contact:
±2, ±4, ±6kV
Air:
±2, ±4, ±8kV
Same as left Floors should by be made of wood, concrete,
or ceramic tile that hardly produces static. If
floors are covered with synthetic material that
tends to produce static, the relative humidity
should be at least 30%.
Electrical fast
transient/burst
IEC 61000-4-4
±2kV
for power supply lines
±1kV
for input/output lines
Same as left Mains power quality should be that of a typical
commercial (original condition feeding the
facilities) or hospital environment.
Surge
IEC 61000-4-5
Differential mode:
± 0.5, ± 1 kV
Common mode:
±0.5, ±1, ±2kV
Same as left Mains power quality should be that of a typical
commercial or hospital environment.
Voltage dips,
short interruptions
and voltage
variations on
power supply

IEC 61000-4-11
< 5% U
T
(>95% dip in U
T
)
for 0.5 cycle
Same as left Mains power quality should be that of a typical
commercial or hospital environment. If the
user of this instrument required continued
operation during power mains interruptions, it
is recommended that this instrument be
powered from an uninterruptible power supply
or a battery.
40% U

(60% dip in U
T
)
for 5 cycles
70% U
T
(30% dip in U

(>95% dip in U
T
)
for 5 seconds

IEC 61000-4-8
3 A/m Same as left It is recommended to use this instrument by
maintaining enough distance from any
equipment that operates with high current.
