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

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.

also
after
power
interruptions/disruptions, it is recommended
to provide the FDM force-distribution
measuring system with power from an
uninterruptible power supply.
