Guidelines
Floors should consist of wood or
concrete or be covered with ceramics.
When the floor is covered with synthetic
materials, the relative humidity should be
no less than 30 %.
The quality of the power supply should
correspond to a typical commercial or
hospital environment.
The quality of the power supply should
correspond to a typical commercial or
hospital environment.
The quality of the power supply should
correspond to a typical commercial or
hospital environment.
If the user of the 7730.65 scale demands
continued function even when the
energy supply is interrupted, we
recommend powering the 7730.65 scale
with an uninterruptible power supply or a
battery.
Magnetic fields at mains frequency
should correspond to the typical values
as found in commercial and hospital
environments.
