Safety Instructions

Follow these instructions to keep this oscilloscope accessory operating in a correct

and safe condition. Observe generally accepted safety procedures in addition to the

precautions specified in this section. 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.

HIGH VOLTAGE WARNING. Risk 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.

DOUBLE INSULATION

PROTECTIVE (EARTH) TERMINAL

Precautions

Avoid personal injury or damage to your equipment by complying with the following

safety precautions:

Use only as specified. The probe is intended to be used only with compatible Teledyne

LeCroy instruments. Use of the probe and/or the equipment it is connected to in a

manner other than specified may impair the protection mechanisms.

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. Observe all terminal ratings.

Connect and disconnect properly. Connect the probe to the measurement instrument

before connecting it to the circuit/signal being tested. De-energize the circuit under

www. .com information@itm.com1.800.561.8187

CP03x/CP03xA Current Probes

test before connecting or disconnecting the probe. Avoid damaging cables 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.

Use the probe only with conductors carrying 300 V or less to avoid short circuits and

accidents that could result in injury or death.

Be sure the conductors measured are insulated with material conforming to

Overvoltage Category I (basic insulation requirement for working voltage of 300 V),

Pollution Degree 2 to prevent short circuits and electric shock when conductors carry

less than 300 V but more than the safe voltage level (SELV limit).

Be careful not to damage the insulation surface when making measurements.

Use only 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.

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.

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.
