73/23/EEC (Low Voltage) as amen-
ded 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.
