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 Hemo-
Cue systems should assure that it is used in such an environment.

Compliance level Electromagnetic environment – guidance
±6 kV contact Floors should be wood, concrete or ceramic tile.
If floors are covered with synthetic material, the
±8 kV air relative humidity should be at least 30 %.
2 kV for power Mains power quality should be that of a typical
supply 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 Mains power quality should be that of a typical
in U) for a 0.5 cycle commercial or hospital environment.
40 %U (60 % dip in If the user of the HemoCue systems requires
U) for 5 cycles continued operation during power mains inter-
ruptions, it is recommended that the HemoCue
70 %U (30 % dip in systems be powered from an uninterruptible
U) for 25 cycles power supply or a battery.
<5 %U (>95 % dip
in U) for 5 seconds
