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 pre-
cautions to avoid misleading results when making measurements in the pres-
ence of electronic interference.
