Guidance and manufacturer's declaration – Electromagnetic immunity
The HemoCue systems are intended for use in the electromagnetic environment specified below. The customer or
user of the HemoCue systems should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Electrostatic discharge ±6 kV contact
(ESD)
IEC 61000-4-2 ±8 kV air
Electrical fast transient/ ±2 kV for power supply
burst lines
IEC 61000-4-4 ±1 kV for input/output
lines
Surge ±1 kV differential mode
IEC 61000-4-5
Voltage dips, short <5 %U (>95 % dip in U)
interruptions and for a 0.5 cycle
voltage variations on
power supply lines 40 %U (60 % dip in U)
for 5 cycles
IEC 61000-4-11
70 %U (30 % dip in U)
for 25 cycles
<5 %U (>95 % dip in U)
for 5 seconds
For explanation of U
see NOTE 1
Compliance level Electromagnetic environment – guidance
±6 kV contact Floors should be wood, concrete or
ceramic tile. If floors are covered with
±8 kV air synthetic material, the relative humidity
should be at least 30 %.
2 kV for power Mains power quality should be that of
supply lines a typical commercial or hospital environ-
ment.
±1 kV for input/
output lines
±1 kV differen- Mains power quality should be that of
tial mode a typical commercial or hospital environ-
ment.
<5 %U (>95 % Mains power quality should be that of
dip in U) for a a typical commercial or hospital environ-
0.5 cycle ment.
40 %U (60 % dip If the user of the HemoCue systems image
in U) for 5 cycles intensifier requires continued operation
during power mains interruptions, it is
70 %U (30 % recommended that the HemoCue systems
dip in U) for image intensifier be powered from an
25 cycles uninterruptible power supply or a battery.
<5 %U (>95 %
dip in U) for
5 seconds
