Floor should be wood, concrete or ceramic tile. If fl oors
are covered with shythetic material, the relative humidity
should be at least 30%.
Mains power quality should be that of a typical commercial

Mains power quality should be that of a typical commer-
cial or hospital environment. If the use of the FT 65 Multi-
function Thermometer requires continued operation dur-
ing power mains interruptions, it is recommended that the
FT 65 Multi-function Thermometer be powered from an
uninterruptible power supply or a battery.
Power frequency magnetic fi elds should be at levels char-
acteristic of a typical location in a typical commercial or
hospital environment.
