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.
