Guidelines and Manufacturer's Statement - Electromagnetic Emission
The FDM force-distribution measuring system is intended for use in the electromagnetic environment described below. The customer
or user of the FDM force-distribution measuring system should ensure that it is operated in such an environment.
Emitted interference
measurements
Compliance
Electromagnetic environment guidelines
RF emissions
acc. to CISPR 11
Group 1
The FDM force-distribution measuring system uses RF energy
exclusively for its internal functions. Therefore its RF emission is very
low and it is unlikely that electronic equipment in close proximity will
experience interference.
RF emissions
acc. to CISPR 11
class B
The FDM force-distribution measuring system is intended for use in
all facilities including those in residential areas and those directly
connected to a public utility network also supplying buildings used for
residential purposes.
Emission of harmonic oscillations
acc. to IEC 61000-3-2
class B
Emission of voltage fluctuations /
flickers acc. to IEC61000-3-3
in compliance
Guidelines and Manufacturer's Statement - Electromagnetic Interference Immunity
The FDM force-distribution measuring system is intended for use in the electromagnetic environment described below. The customer
or user of the FDM force-distribution measuring system should ensure that it is operated in such an environment.

Flooring should be of wood or concrete or
laid with ceramic tiles. If the flooring is
made of synthetic material, the relative
humidity must be at least 30%.

The quality of the supply voltage should be
the same as the voltage of a typical
business or hospital environment.

The quality of the supply voltage should be
the same as the voltage of a typical
business or hospital environment. If the
user of the FDM force-distribution
measuring system requires the continuation
of functionality also after power
interruptions/disruptions, it is recommended
to provide the FDM force-distribution
measuring system with power from an
uninterruptible power supply.
