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.
UT
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
model BASE800 requires continued
operation during power mains
interruptions, it is recommended
that the model BASE800 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.
