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 elds 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.
