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.
