However, electrical noise or intense electromagnetic fields in the vicinity of the equip-
ment 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.
