Safety Instructions
Follow these instructions to keep the probe operating in a correct and safe condition.
Observe generally accepted safety procedures in addition to the precautions specified
here. The overall safety of any system incorporating this accessory is the responsibility
of the assembler of the system.
Symbols
These symbols appear on the probe body or in documentation to alert you to important
safety considerations.
CAUTION, possibility of electric shock.
CAUTION of damage to probe or instrument, or WARNING of hazard to health.
Attend to the accompanying information to protect against personal injury or
damage. Do not proceed until conditions are fully understood and met.
Do not apply around or remove from UNINSULATED HAZARDOUS LIVE
conductors which may render electric shock, electric burn, or arc flash.
Equipment protected by double insulation or reinforced insulation.
CAUTION, hot surface.
Precautions
Comply with the following safety precautions to avoid personal injury or
damage to your equipment:
Use only as specified. The probe is intended to be used only with compatible Teledyne
LeCroy instruments. Using the probe and/or the equipment it is connected to in a
manner other than specified may impair the protection mechanisms.
Do not use the probe for measurements on Mains circuits. The probe should only be
applied around or removed from insulated limited energy circuit conductors that are
not directly connected to the mains.

CP03x/CP03xA Current Probes

Do not overload; observe all ratings. To avoid electric shock or fire, do not connect the
current probe to any wire that carries voltages or currents that exceed the ratings of
the probe.
Connect and disconnect properly. Connect the probe to the measurement instrument
before connecting to the circuit/conductor being measured. Avoid damaging the cable
through excessive bending.
Never install or remove the probe on bare conductors which are energized. The
transformer core and shield are grounded but not insulated and may contact the
conductor when the locking lever is open.
Be careful not to damage the insulation surface when making measurements. Before
clamping to the conductor being measured, check that the insulation on the conductor
is undamaged, and take care not to damage the insulation when clamping the
conductor. Any damage to the insulation could cause an electric shock.
Use only indoors and within the operational environment listed. Do not use in wet or
explosive atmospheres.
Do not remove the probe's casing. Touching exposed connections may result in electric
shock.
Keep product surfaces clean and dry.
Comply with the maximum input current vs. frequency derating when measuring
current that includes a high frequency component. Using the probe at high frequencies
or in strong magnetic fields may cause the device to become abnormally hot, resulting
in fire, equipment damage or burns.
Do not operate with suspected failures. Before each use, inspect the probe and
accessories for any damage such as tears or other defects in the probe body, cable
jacket, accessories, etc. If any part is damaged, cease operation immediately and
sequester the probe from inadvertent use.
NOTE: Depending on the amplitude and frequency of the current being measured, the
sensor head may emit a resonant sound. This sound may also occur during
demagnetizing operation, but it does not represent a malfunction (device failure).

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 CP030-3M probe has a 10 MHz bandwidth and
is designed to measure continuous currents up to 30 Amp.
NOTE: All CP030A probes, regardless of cable length, will indicate default probe
bandwidth of 50 MHz in the Attributes section of the Probe dialog.
The CP031 and CP031A have a 100 MHz bandwidth and are designed to measure
continuous currents up to 30 Amp.
The CP03x probes are compatible with any Teledyne LeCroy oscilloscope with a ProBus
interface running Windows XP Professional®or later.
The CP03xA probes are compatible with most Teledyne LeCroy oscilloscopes with a
ProBus interface running X-Stream™ firmware version 7.8.x.x or later. See table below.

Safety Ratings
Probe Designation1Type D
Measurement Category 2No rated measurement category
Safe Voltage Rating 3Use only on fully insulated conductors
Pollution Degree 42
Definitions (per IEC/EN 61010-2-032:2012)
1. Type D current probe is intended to be applied around or removed from insulated conductors.
2. No rated measurement category; not intended for measurements on circuits directly connected to the
Mains supply. Not rated for measurements within Measurement Categories II, III, or IV.
3. Not rated for measurements on uninsulated conductors.
4. Pollution Degree 2 refers to operating environment where normally only dry, non-conductive pollution
occurs. Temporary conductivity caused by condensation should be expected.
NOTE: Because of the marking requirements per safety standard EN 61010-2-032:2012 (Third Edition), the
measurement category rating that was on the CPxxx probes originally certified per EN 61010-2-032:2002
(Second Edition) has been removed from the product label. However, this change does not reduce the
measurement capability or the level of protection offered by the new probe design.

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, or application of static electricity.
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.

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.
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.
CAUTION: 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.

Operating with an Oscilloscope
When 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.
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.

CP03x/CP03xA Current Probes
12
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.
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, CP030-3M, 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 7.8.x.x or higher for CP03xA. To confirm the version installed, choose
Utilities > Utilities Setup from the oscilloscope menu bar, then open the Status tab.
