Introduction
The CP030, CP030A, CP031, and CP031A current probes are designed for easy, highly
accurate current measurements. The compact probes offer wide bandwidth with
over-current protection.
The probes utilize a combination of Hall-effect and transformer technology which
enables measurements to be made on DC, AC and impulse currents.
The CP030 and CP030A have a 50 MHz bandwidth and are designed to measure
continuous currents up to 30 Amp.
The CP031 and CP031A have a 100 MHz bandwidth and are designed to measure
continuous currents up to 30 Amp.
The probes can be used with any Teledyne LeCroy instrument with a ProBus interface,
or by using a ProBus interface adapter. With the ProBus interface, the probe becomes
an integral part of the measuring instrument. The bandwidth limit, Auto Zero and
Degauss functions are all controlled from the instrument’s touch screen user interface.
The interface provides power to the probe, so no external power supply is needed.

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.
Connecting to the Test Instrument
The probe has been designed for use with the Teledyne LeCroy instruments equipped
with the ProBus interface. When you attach the probe output connector to the
instrument’s input connector, the instrument will:
• Recognize the probe model
• Set the input termination to 1 MΩ
• Activate the probe control functions in the touch screen user interface.
Connecting to the Test Circuit
The probe 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 back 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.

Operator’s Manual
CAUTION: Never use this probe on bare conductors. The core and shield are
probe or the circuit under test.
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.
grounded and any voltage applied to the conductor may cause damage the
Operating with an Oscilloscope
When the probe is connected to a Teledyne LeCroy oscilloscope, the displayed scale
factor and measurement values will be adjusted to account for the effective gain of the
probe.
A/div, Offset, and Coupling, and Bandwidth (BWL) are controlled from the Channel
setup (Cx) dialog.
Channel setup dialog with Probe dialog behind it.
The probe’s attributes are shown on the Probe dialog, which appears behind the
Channel dialog when a probe is detected. The Probe dialog also contains controls for
Auto Zero and Degauss.
Probe dialog.

Page 15
CP03x/CP03xA Current Probes
Probe A/div and Attenuation
The front panel Volts/div knob controls the oscilloscope’s scale factor and the probe’s
internal attenuation to give full available dynamic range from 10mA/div to 15 A/div for
CP030 and CP031, or 1 mA/div to 15 A/div for CP030A and CP031A. CP031A and
CP031A will automatically adjust attenuation based on the A/div setting.
Alternatively, A/div may be controlled from the channel setup dialog (Cx).
Bandwidth Limit
The probe is capable of switching from Full (maximum bandwidth) to 20 MHz
bandwidth by changing the Bandwidth setting on the Cx dialog.
AC Coupling
In general, using offset to adjust a DC current on the screen is the preferred method to
measure transient signals in the presence of a larger DC currents. The offset has limits
that will cause a signal that is beyond the linear operating range of the probe to go off
the screen, preventing measurement errors.
There are times, however, when it is convenient to use AC coupling to remove the DC
component of the measured signal from the measurement. Selecting AC uses the
scope AC coupling at the probe output to remove any steady state value from the
displayed voltage.
NOTE: Since this AC coupling is on the probe output, DC current beyond the linear
range of the probe will cause the probe to saturate and make the displayed waveform
inaccurate. It is important not to exceed the maximum linear input values when using
AC coupling. The maximum DC input current is 30A when the probe is in 0.1 V/A
sensitivity (>100mA/div), and 5A when the probe is in 1 V/A (≤100mA/div).
Auto Zero
The Probe dialog incorporates an Auto Zero function to remove the DC offset from the
current probe. Auto Zero must be invoked by the user. After several minutes of
warm-up, or when the probe is exposed to a large shift in ambient temperature, some
DC offset drift may occur. Open the Probe dialog and touch AUTO ZERO.
10
Page 16
Operator’s Manual
Degauss
If the probe has been magnetized by external magnetic field or by excessive input, the
core can be demagnetized by degaussing. The demagnetizing process takes about 5
seconds and should always be performed before taking a measurement.
Without clamping the probe around a conductor, slide the opening lever to close and
lock the probe. Open the Probe dialog and touch DEGAUSS.
An Auto Zero is automatically performed as part of the degauss cycle.
Performance Verification
This procedure can be used to verify the warranted characteristics of the probe. The
recommended calibration interval for the models CP030, CP030A, CP031, and CP031A
Current Probes is one year. The complete performance verification procedure should be
performed as the first step of annual calibration. Performance verification can be
completed without removing the probe covers or exposing the user to hazardous
voltages. Test results can be recorded on a photocopy of the Test Record provided at
the end of the manual.
The warranted characteristics of the probe are valid at any temperature within the
Environmental Characteristics listed in the Specifications. However, some of the other
test equipment used to verify the performance may have environmental limitations
required to meet the accuracy needed for the procedure. Make sure that the ambient
conditions meet the requirements of all the test instruments used in his procedure.
NOTE: Operation of the probe as described requires software version 4.3.0.0 or higher
for CP03x and 7.7.1.Xa or higher for CP03xA. To confirm the version installed on the
instrument, choose Utilities > Utilities Setup from the menu bar, then open the Status
tab. CP03xA probes are not compatible with WaveSurfer 3000 oscilloscopes.
Test Equipment Required
The following table lists the test equipment and accessories (or their equivalents)
which are required for performance verification of the CP03x/CP03xA Current Probes.
Because the input and output connector types may vary on different brands and
models of test instruments, additional adapters or cables may be required.
