Electromagnetic emissions
Compliance Electromagnetic environment - guidance
Group 1 /Class B The Welch Allyn Masted Scale uses RF energy only for its internal
function. Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment.
Class B
The Welch Allyn Masted Scale is suitable for use in all establishments
other than domestic and those directly connected to the public low-
voltage power supply network that supplies buildings used for domestic
purposes.

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

of the Welch Allyn Masted Scale requires
(30 % dip in
continued operation during power mains
interruptions, it is recommended that the
Welch Allyn Masted Scale be powered from an
uninterruptible power supply or a battery.
(>100 % drop
Power frequency magnetic fields should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
