NOTE: 

This instrument complies with class ll, overvoltage CAT lll, 600V of the
IEC1010-1 (EN61010-1) standard and pollution degree 2 in accordance
with IEC-664 indoor use.

This instrument also complies with the 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. Measurement
instruments will also respond to unwanted signals that may be present.
Users should exercise care and take appropriate precautions to avoid
misleading results in the presence of electromagnetic interference.
