CAUTION
• Do not subject the instrument to vibrations or shocks when transporting
and handling it. Be especially careful to avoid dropping it.
• Do not store or operate the instrument in an environment with direct
sunlight, high temperature, high humidity, or condensation. The
instrument may be deformed, or deteriorated in insulation, and it may
not meet the specifications.
• Before using the instrument, inspect and check the operation for
malfunctions due to storage or transport conditions. If a malfunction is
found, contact your dealer or YOKOGAWA representative.
• The instrument is not dustproof or waterproof. Do not use it in a dusty or
wet environment.
• The sensor head is a precision assembly composed of a molded
component, a ferrite core and a Hall effect element. Handle the
instrument with care as it may be damaged by sudden changes in
ambient temperature, mechanical stress or shock.
• The matching surfaces of the sensor head are precision ground
.
Handle
the instrument with care as scratches on the surfaces may impair
performance.
• Gently wipe off any dust or dirt on the matching surfaces of the sensor
head with a soft cloth
.
It may generate resonance noise or impair
performance.
• Do not bend or pull the sensor cable or power cable
to avoid damage
due to disconnection.
• Current sensors can be damaged by static electricity. Be careful not to
apply static electricity to the instrument including the following cases.
• Touching the sensor head with an object charged with static electricity
• Touching the sensor head with an object with an electrical potential
difference
• A user charged with static electricity touching the core surface when
cleaning the matching surfaces of the sensor head
(When cleaning the surfaces, take static electricity measures such as
wearing an antistatic wrist strap.)
• Gently wipe the instrument with a soft cloth moistened with a small
amount of water or mild detergent. Do not use detergents containing
organic solvents such as benzine, alcohol, acetone, ethers, ketones,
thinners or gasoline. They may deform or discolor the instrument.
• When the power is on, keep the sensor head closed, except when
clamping the conductor under measurement. Leaving it open may
damage the instrument.
