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
