Safe Probing

CAUTION
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.
CAUTION
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.
CAUTION
Foreign substances such as dust on the contact surfaces of the sensor
head can cause acoustic resonance and degrade measurement, so it
should be cleaned by gently wiping with a soft cloth.
CAUTION
To avoid damaging the sensor cable and power supply cable, do not
bend or pull the cables.
CAUTION
Do not apply a static electricity or other source of high voltage to the
sensor. Doing so may damage its internal Hall elements and circuitry.
CAUTION
Avoid stepping on or pinching the cable, which could damage the cable
insulation.
CAUTION
Keep the cable well away from heat sources, as bare conductors could
be exposed if the insulation melts.
CAUTION
When the power is on, keep 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.
