Electromagnetic
environment - guidance
Floors should be wood,
concrete or ceramic tile. If floor
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 ECG100G ECG
requires continued operation
during power mains dip &
interruptions, it is
recommended that the
ECG100G ECG 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.
