Instruments with plastic housing as well as in four-wire or Ex-d-ia
version are designed for use in an industrial environment. Neverthe-
less, electromagnetic interference from electrical conductors and
radiated emissions must be taken into account, as is usual with a
class A instrument according to EN 61326-1. If the instrument is used
in a different environment, the electromagnetic compatibility to other
instruments must be ensured by suitable measures.
