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.
