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 (ESD) ±6 kV contact
IEC 61000-4-2

Compliance level Electromagnetic environment – guidance
±6 kV contact Floors should be wood, concrete or ceramic tile. If
floors are covered with synthetic material, the relative
±8 kV air humidity should be at least 30 %.
2 kV for power supply Mains power quality should be that of a typical
lines commercial or hospital environment.
±1 kV for input/
output lines
±1 kV differential Mains power quality should be that of a typical
mode commercial or hospital environment.
<5 %U (>95 % dip in U) Mains power quality should be that of a typical
for a 0.5 cycle commercial or hospital environment.
40 %U (60 % dip in U) If the user of the HemoCue systems requires continued
for 5 cycles operation during power mains interruptions, it is
recommended that the HemoCue systems be powered
70 %U (30 % dip in U) from an uninterruptible power supply or a battery.
