Safety Instructions

This section contains instructions that must be observed to keep this oscilloscope accessory operating in

a correct and safe condition. You are required to follow 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 may appear on the probe body or in this manual to alert you to important safety

considerations.

WARNING. High Voltage, risk of electric shock.

CAUTION. Potential for damage to probe or instrument it is connected to. Attend to the accompanying

information to protect against personal injury or damage. Do not proceed until conditions are fully understood

and met.

ELECTROSTATIC DISCHARGE (ESD) HAZARD. The probe is susceptible to damage if anti-static measures

are not taken.

DOUBLE INSULATION

PROTECTIVE (EARTH) TERMINAL

Precautions

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

connecting the test leads to a circuit/signal being tested.

Use only within operational environment listed. Do not use in wet or explosive atmospheres.

Use indoors only.

Keep product surfaces clean and dry.

Be careful with sharp tips. The tips may cause bodily injury if not handled properly.

Do not operate with suspected failures. Do not use the probe if any part is damaged. Cease

operation immediately and sequester the probe from inadvertent use.

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

CP500 Current Probe

2 922176-00 Rev A

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.

To avoid short circuits and accidents that could result in injury or death, use the CP500 current

probe only with conductors carrying 600 V (CAT II) or 300 V (CAT III) or less.

To prevent short circuits and electric shock when conductors being measured carry less than

600 V (CAT II) or 300 V (CAT III), but more than the safe voltage level (SELV-E) make sure that the

conductors to be measured are insulated with material conforming to:

oOvervoltage Category III, basic insulation requirement for working voltage of 300 V

oPollution degree 2

Operating Environment

The accessory is intended for indoor use and should be operated in a clean, dry environment. Before

using this product, ensure that its operating environment is maintained within these parameters:

Temperature: 0° to 40° C

Humidity: ≤ 80% relative humidity (non-condensing)

Altitude: up to 2000 m (6562 feet)

Overview

Description

The CP500 uses a combination of Hall effect and transformer technology which enables measurements

to be made on DC, AC and impulse currents. It has a 2 MHz bandwidth and is designed to measure

continuous currents up to 500 Amp.

The probe can be used with a WaveRunner, WavePro, or LC series oscilloscope with firmware 4.3.0.0 or

higher. With the ProBus interface, the CP500 becomes an integral part of the oscilloscope. The

bandwidth limit, auto zero and degauss functions are all controlled from the oscilloscope’s graphical

user interface. The oscilloscope provides power to the probe, so no external power supply is needed.

Key Features

• Highly accurate current measurements

• Easy current measurements

• Wide bandwidth

• Compact

• Over-current protected

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 the Probe to the Test Instrument

The CP500 probe has been designed for use with the WaveRunner, WavePro and LC series Teledyne

Lecroy oscilloscopes equipped with the ProBus interface. Attach the probe output connector to the

oscilloscope input connector. The oscilloscope will recognize the probe, set the oscilloscope input

termination to 1 MΩ and activate the probe control functions in the user interface.

Connecting the Probe to the Test Circuit

The CP500 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 the locking lever, 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. Press the probe jaws together around the conductor until the jaws click shut.

4. Slide the locking lever on the sensor head towards the front of the probe until the "UNLOCK”

indication disappears and the "LOCK" indication appears.

NOTE: 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.
