Electromagnetic Environment – Guidance
Floors should be wood, concrete or ceramic
tile. If floors are covered with synthetic
material, the relative humidity should be at
least 30%.
Mains power quality should be that of a
typical commercial or hospital environment.
Mains power quality should be that of a
typical commercial or hospital environment.
Mains power quality should be that of a
typical commercial or hospital environment.
If the user of the EUT image intensifier
requires continued operation during power
mains interruptions, it is recommended that
the EUT image intensifier be powered from
an uninterruptible power supply or a battery.
Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or hospital
environment.
