•
To avoid damage to the device, protect it from vibration or shock
during transport and handling, and be especially careful to avoid
dropping.
•
Do not store or use the device where it could be exposed to direct
sunlight, high temperature, humidity, or condensation. Under such
conditions, the device may be damaged and insulation may
deteriorate so that it no longer meets specifications.
•
Before using the device the first time, verify that it operates normally
to ensure that the no damage occurred during storage or shipping. If
you find any damage, contact your dealer or Agilent representative.
•
This device is not designed to be entirely water- or dust- proof. To
avoid damage, do not use it in a wet or dusty environment.
•
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.
•
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.
•
To avoid damaging the sensor cable and power supply cable, do not
bend or pull the cables.
•
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.
