The instrument can be so influenced by electrostatic charges
and other electromagnetic phenomena that it no longer func-
tions within the given technical specifications.
The following measures reduce or eliminate the effect of such
disturbances: Avoid fitted carpets; ensure potential equaliza-
tion; carry out experiments on a conductive, earthed surface,
use screened cables, do not operate high-frequency emitters
(radios, mobile phones) in the immediate vicinity.
This instrument complies with Class A, Group 1 of the
EN 55011 norm and it is only permitted to operate unlimitedly
outside of residential areas. Should electromagnetic distur-
bances, despite the limitations of usage to a technical room
of a school or other place of education, occur in a surround-
ing residential area, then it can be demanded of the operator
that he or she carries out appropriate measures (e.g. screen-
ing, longer distance away from sensitive equipment, shorter
operating principles, as short as possible connecting cables
etc.) at his or her own cost.
