Compliance Electromagnetic
Level Environment Guidance
± 6 kV contact Floor should be wood,
concrete, or ceramic tile. If
± 8 kV air
floors are covered with
synthetic material, the
relative humidity should be
at least 30%.
± 2 kV for power Mains power quality should
supply lines be that of a typical
commercial and/or hospital
± 1 kV for input/
environment
output lines
± 1 kV differential Mains power quality should
mode be that of a typical
commercial and/or hospital
± 2 kV common
environment
mode
<5% UT Mains power quality should
be that of a typical
(>95% dip in UT)
commercial and/or hospital
for 0.5 cycle
environment.
40% UT
If the user of the oximeter
requires continued
(60% dip in UT)
operation during power
for five cycles
mains interruption, it is
70% UT
recommended that the
oximeter be powered from
(30% dip in UT)
an uninterruptible power
for 25 cycles
supply or battery.
<5% UT
Note: UT is the AC main's
(95% dip in UT)
voltage prior to
for five seconds application of the test
level.
3 A/m If image distortion occurs, it
may be necessary to position
the oximeter further from
the sources of power
frequency magnetic fields or
to install magnetic shielding.
The power frequency
magnetic field should be
measured in the intended
installation location to
assure that it is sufficiently
low.
