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.

www. .com information@itm.com1.800.561.8187

CP150 and CP500 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 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).

Operator’s Manual

Introduction

The CP150 and CP500 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 CP150 has a 10 MHz bandwidth and is designed to measure continuous currents

up to 150 Amps. The CP150-6M has a 5 MHz bandwidth and is designed to measure

continuous currents up to 150 Amps.

NOTE: All CP150 probes, regardless of cable length, will indicate default probe

bandwidth of 10 MHz in the Attributes section of the Probe dialog.

The CP500 has a 2 MHz bandwidth and is designed to measure continuous currents up

to 500 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.

Safety Ratings

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 must 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.
