CP030 Current Probe

Operation

Precautions

NOTE: 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.

Connecting the Probe to the Test Instrument

The CP030 probe has been designed for use with the WaveSurfer, WaveRunner 6000, WavePro 7000,
and WaveMaster series Teledyne Lecroy oscilloscopes equipped with the ProBus interface. Attach the
probe output connector to the oscilloscope input connector. The oscilloscope will recognize the probe,
set the oscilloscope input termination to 1 MΩ and activate the probe control functions in the user
interface. To use the CP030 with a WaveMaster scope, the AP-1M impedance adapter is required.

Connecting the Probe to the Test Circuit

The CP030 has been designed with a movable split core, eliminating the need to break the conductor for
the core to slip around the conductor.
To connect:
1. Pull the slider, so that the clamp opens.
2. Align the sensor so that the current direction indicator corresponds to the direction of current
flow in the conductor.
3. Close the slider on the sensor head until the "UNLOCK' indication disappears and the "LOCK"
indication appears.
4. Verify that the opening lever is firmly locked and the clamp is securely closed.
NOTE: Never use this probe on bare conductors. The core and shield are grounded and any voltage
applied to the conductor may cause damage the probe or the circuit under test.
