Safety
10
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
external magnetic fields, such as transformers and high-current
conductors, or in locations subject to strong external electric fields, such as
radio transmission equipment.
