Guidance and manufacturer’s declaration - electromagnetic immunity
The OEV262H is intended for use in the electromagnetic environment specified below. The customer or the user of the OEV262H
should assure that it is used in such an environment.
Immunity test IEC 60601 test
level
Compliance level Electromagnetic environment - guidance
Electrostatic
discharge (ESD)
IEC 61000-4-2
±2, ±4, ±6 kV
contact
±2, ±4, ±8 kV air
Same as left Floors should 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
±2 kV for power
supply lines
±1 kV 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
±0.5, ±1 kV
differential mode
±0.5, ±1, ±2 kV
common mode
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
input lines
IEC 61000-4-11
< 5% U
T
(> 95% dip in U
T
)
for 0.5 cycle
40% U
T
(60% dip in U
T
)
for 5 cycles
70% U
T
(30% dip in U
T
)
for 25 cycles
< 5% U
T
(> 95% dip in U
T
)
for 5 sec
Same as left Mains power quality should be that of a typical commercial or
hospital environment. If the user of the OEV262H requires
continued operation during power mains interruptions, it is
recommended that the OEV262H be powered from an
uninterruptible power supply or a battery.
Power frequency
(50/60Hz)
magnetic field
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.
Definition: U
T
is the a.c. mains voltage prior to application of the test level.
