Electromagnetic environment – guidance
Floor should be wood, concrete or ceramic tile. If floors
are covered with shythetic material, the relative humidity
should be at least 30%.
Mains power quality should be that of a typical com-
mercial or hospital environment.
Mains power quality should be that of a typical com-
mercial or hospital environment.
Mains power quality should be that of a typical com-
mercial or hospital environment. If the use of the SFT77
Multi-function Thermometer requires continued ope-
ration during power mains interruptions, it is recom-
mended that the SFT77 Multi-function Thermometer
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 commer-
cial or hospital environment.
