• To prevent electric shock, do not allow the unit to become wet and
WARNING do not use the unit when your hands are wet.
• Do not subject the unit to vibrations or shocks during transport or
CAUTION
handling. Be especially careful to avoid dropping the unit.
• Do not store the unit where it will be exposed to direct sunlight,
high temperature, high humidity, or condensation. If exposed to such
conditions, the unit may be damaged, the insulation may deteriorate,
and the unit may no longer satisfy its specifications.
• Before using the unit, inspect it and check the operation to make
sure that the unit was not damaged due to poor storage or transport
conditions. If damage is found, contact your dealer or Agilent
representative.
• This unit is not constructed to be waterproof or dustproof, so do not
use it in a very dusty environment or in one where it will get wet.
• The sensor head is a precision assembly including a molded component,
a ferrite core, and a Hall effect element. It may be damaged if subjected
to sudden changes in ambient temperature, or mechanical strain or
shock, and therefore great care should be exercised in handling it.
• The matching surfaces of the sensor head are precision ground, and
should be treated with care. If these surfaces are scratched,
performance may be impaired.
• Do not bend or pull the sensor cable and power supply cable in order
to avoid damaging the sensor cables.
• Gently wipe dirt from the surface of the unit with a soft cloth moistened
with a small amount of water or mild detergent. Do not try to clean
the unit using cleaners containing organic solvents such as benzine,
alcohol, acetone, ether, ketones, thinners, or gasoline. They may cause
discoloration or damage.
• To avoid scratching the surfaces of the Hall effect elements, keep the
core section of the sensor closed, except when clamping it around the
conductor to be measured.
• Accurate measurement may be impossible in locations subject to strong
NOTE
external magnetic fields, such as transformers and high- current
conductors, or in locations subject to strong external electric fields,
such as radio transmission equipment.
