CP150 and CP500 Current Probes
Operation
Precautions
The sensor head is a precision assembly consisting of a molded component with a
ferrite core and a Hall effect element. It may be damaged if subjected to sudden
changes in temperature, mechanical strain or shock.
The mating surfaces of the sensor are precision ground and should be treated with
care. If there is any type of dust or dirt on the mating surfaces of the sensor head,
measurements may be impaired.
Accurate measurements may not be possible in locations subject to strong magnetic
fields such as transformers and high-current conductors, or in locations subject to
strong external electric fields.

WARNING: Comply with the derating characteristics of the probe when
measuring current that includes a high frequency component, and never
measure any current that exceeds the rated current. Using the probe at high
frequencies or in strong magnetic fields may cause the probe head to
become abnormally hot, resulting in fire, equipment damage or burns.
CAUTION: Do not touch the probe head until it has had sufficient time to
cool after disconnecting the probe from the circuit. Using the probe near the
current and ambient temperature upper limits for extended lengths of time
may cause the probe head surface to become hot to the touch.
CAUTION: Do not use this probe for making measurements on Mains
Circuits. Using the probe on uninsulated hazardous live conductors may
result in electric shock, electric burn, or arc flash.
