Guidelines and Manufacturer's Statement - Electromagnetic Emission
The FDM-T force-distribution measuring system is intended for use in the electromagnetic environment described below. The custom-
er or user of the FDM-T force-distribution measuring system should ensure that it is operated in such an environment.

Electromagnetic environment guidelines
RF emissions
acc. to CISPR 11
Group 1
The FDM-T 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.

class B
The FDM-T 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

The quality of the supply voltage should be
the same as the voltage of a typical busi-
ness or hospital environment. If the user of
the FDM-T force-distribution measuring
system requires the continuation of func-
tionality
also
after
power
interrup-
tions/disruptions, it is recommended to
provide the FDM-T force-distribution meas-
uring system with power from an uninter-
ruptible power supply.

Not tested as no influence
is possible on the device
within the specified test
level. (see Note B)
Magnetic fields of the mains power fre-
