PRECAUTIONS
11
• 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
precisely ground, and should be treated with care.
If these surfaces are scratched, performance may
be impaired.
• To avoid damaging the sensor cables, do not bend
or pull the sensor cable and power supply cable.
• To clean the device, wipe it gently with a soft cloth
moistened with water or mild detergent. Never
use solvents such as benzene, alcohol, acetone,
ether, ketones, thinners or gasoline, as they can
deform and discolor the case.
• When the power is on, keep the core section of the
sensor closed, except when clamping them onto
the conductor to be measured. The facing surface
of the core section can be scratched while it is
open.
• Keep the clamp jaws and core slits free from
foreign objects, which could interfere with
clamping action.
• Keep the sensor head closed when not in use, to
avoid accumulating dust or dirt on the mating core
surfaces, which could interfere with clamp
performance.
• Avoid stepping on or pinching the cable, which
could damage the cable insulation.
• Keep the cables well away from heat sources, as
bare conductors could be exposed if the insulation
melts.
