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.

*Compatible if running Windows XP Professional and X-Stream 7.8.x.x or later. †Must be upgraded to Windows XP
Professional, not Windows XP Embedded. Contact your regional service center regarding upgrades.

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.
