- EMC: Conforms to EN61326-1. This product complies with
requirements of the following European Community Directives:
89/ 336/ EEC (Electromagnetic Compatibility) and 73/ 23/ EEC
(Low Voltage) as amended by 93/ 68/ EEC (CE Marking). However,
electrical noise or intense electromagnetic fields in the vicinity of
the equipment may disturb the measurement circuit. Measuring
instruments will also respond to unwanted signals that may be
present within the measurement circuit. Users should exercise care
and take appropriate precautions to avoid misleading results when
making measurements in the presence of electronic interference.
