sss

Do not overload; observe all ratings. To avoid electric shock or re, 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 test 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 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 elds
may cause the device to become abnormally hot, resulting in re, 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).

6) Degaussing and Zero Setting Indicator
After pressing the degaussing / zero button, the indicator light will be green, and after degaussing,
the indicator light will turn off. The buzzer will make two short beeps after successful degaussing.
The buzzer will make an extended beep of about one second if degaussing failed. See 8 below.
7) Range LED Indicator
The green LED indicates the selected range.
8) Degauss / auto zero button
Frequent usage of the T3CP current probe will generate a residual magnetic eld within the
measurement jaw. It is recommended to degauss and auto-zero before a measurement for better
measurement precision. Press the degaussing and auto zero button to trigger the process (should
be around 5s). Remove any DUT from the measurement jaw before degaussing. See 6 above.
9) High / Low Range Selection button
Select the high or low range depending on the measurement being made. Set the oscilloscope
scaling accordingly. See the table below.
10) Power Supply Connection Socket
Connect the supplied external wall socket power supply to the T3CP current probe at this point.
Making Measurements
Before using the probe, check that the preparations described in Safe Probing have been undertaken.
• Inspect the current probe, power supply and cable to ensure that there is no damage. If the
current probe, power supply or cable are damaged please contact Teledyne LeCroy service centre
to arrange repair.
• The output of the current probe is terminated internally. Use the high input impedance 1 MΩ setting
on the oscilloscope’s input when making measurements. Set the oscilloscope’s input coupling to
DC. With the oscilloscope input grounded, adjust the oscilloscope’s trace to the zero position.
Connect the probe’s output BNC connector to the oscilloscope’s input BNC connector using a BNC
to BNC cable. If the oscilloscope input impedance is set to 50Ω, the measurement data will be
incorrect.

• Connect the power supply to probe and the power indicator will light. Select the appropriate
measurement range using the Range Key.
• Ensure that the probe sensor is NOT clamped around any conductors. Slide the probe’s Opening
Lever into the LOCKED position as shown in Figure. Conrm that the sensor head is properly
closed.
• Degauss / auto-zero the probe before making a measurement. The degauss / auto-zero button
should be pressed. The probe will demagnetize the jaw measurement core and set the output to
zero voltage. This is necessary if the jaw core has become magnetized through switching the
power on and o, or by general measurement use. Always carry out degaussing and Zero Setting
before making a measurement and without the DUT in the clamp. The degaussing and Zero Setting
process takes a few seconds. During degaussing and Zero Setting, a demagnetizing waveform is
output and can be seen on the oscilloscope. This waveform is generated internally within the T3CP
current probe and is for the demagnitizing process, it has no useful meaning for the user.
• After degaussing and Zero Setting, the T3CP current probe buzzer will make two short beeps. If
degaussing and Zero Setting failed, the buzzer will make a single beep, for one second. If the
degaussing failed then ensure that no DUT or measurement conductor is in the measurement
jaws, lock the jaws and retry the degaussing process.
• Do not degauss / demagnetize while the DUT conductor being measured is clamped within the
measurement jaws. This could damage the components of the circuit being measured since the
degaussing waveform may be induced into the DUT conductor. For the same reason, ensure that
the DUT conductor being measured is not clamped within the measurement jaws when connecting
power to the current probe. Demagnetizing waveforms are generated when connecting and
switching on the T3CP current probe power supply.
• To make a measurement slide the opening lever to the open / unlocked position and open the
sensor head jaws.

• Align the probe so that the probe’s current direction indication corresponds to the direction of
current ow through the conductor to be measured, as shown below. Also, align the clamp so that
the conductor is in the center of the sensor aperture.
• Slide the opening lever on the sensor head to the lock position until the UNLOCK indication
disappears. Check that the opening lever is rmly locked, and the sensor head securely closed.
You are now ready to make the measurement.
Safe Probing
This device is designed to comply with Safety Standards and has been thoroughly tested for safety
prior to shipment. However, mishandling during use could result in injury or death, as well as damage
to the device. Be certain that you understand the instructions and precautions in the manual before
use. We disclaim any responsibility for accidents or injuries not resulting directly from device defects.
To avoid short circuits and potentially life-threatening hazards, follow these warnings and precautions:
• Never attach the clamp to a circuit that operates over the maximum rated voltage to earth.
• Do not clamp around bare conductors during measurement.
• While clamping and measuring, do not touch the clamp in front of the barrier, or the conductor
being measured.
• Be careful to avoid damaging the DUT conductor insulation while taking measurements.
• Make sure that the oscilloscope connected to this device's output BNC connector is equipped with
protective earthing with double-insulation construction.
• Do not allow the T3CP current probe to get wet, and do not take measurements with wet hands.
This may cause an electric shock.
• Read and observe all warnings and precautions relating to electrical safety for the measuring
instrument (typically an oscilloscope) being connected to the probe.
• Do not store or use the probe where it could be exposed to direct sunlight, high temperature,
humidity, or condensation. Under such conditions, the probe may be damaged and insulation may
deteriorate so that it no longer meets specications.

Page 8
• Before using the probe for the rst time, verify that it operates normally to ensure that no damage
has occurred during storage or shipping. If you nd any damage, contact your dealer or a
Teledyne LeCroy representative.
• This device is not designed to be water or dust proof. To avoid damage, do not use it in a wet or
dusty environment.
• The sensor head is a precision assembly including moulded components, a ferrite core, and a Hall
Eect element. It may be damaged if subjected to sudden changes in temperature, mechanical
strain or shock, and therefore great care should be exercised in handling it. Avoid damage to the
T3CP probe by protecting it from vibration or shock during transport and handling, and be
especially careful to avoid dropping.
• The matching surfaces of the sensor head (jaws) are precision ground, and should be treated with
care. If these surfaces are scratched, performance may be impaired.
• Foreign substances such as dust on the contact surfaces of the sensor head can cause acoustic
resonance and degrade measurement, so it should be cleaned by gently wiping with a soft cloth.
• To avoid damaging the sensor cable and power supply cable, do not bend or pull the cables.
• When the power is on, it is recommended to keep the jaws closed, except when clamping them
onto the conductor to be measured. The facing surfaces of the core section can be scratched
whilst it is open.
• Do not place any unclamped conductor with an electric current of a frequency of 10 kHz or more
near the sensor head. Current owing in the conductor nearby may heat up the sensor head and
cause its temperature to rise, leading to damage to the sensor. For example, when one side of a
out-and-return conductor is clamped and the other side is also placed near the sensor head, even
if the electric current is lower than the maximum current, electric currents in both conductors will
heat up the wires and raise the T3CP probe temperature. This could cause damage to the sensor.
• The maximum continuous input range is based on heat that is internally generated during
measurement. Never input current in excess of this level. Exceeding the rated level may result in
damage to the probe.
• The maximum continuous input range varies according to the frequency of the current being
measured. See the Maximum Continuous Input Current graphs.
• If excess current is input, generated heat activates a built-in safety function that blocks normal
output. If this happens, remove the input immediately (remove the sensor from the conductor
being measured or reduce the input current to zero). Wait until the sensor has had sucient time
to cool before resuming operation.
• Even if the input current does not exceed the rated continuous maximum, continuous input for an
extended period of time may result in activation of the safety circuit to prevent damage resulting
from heating of the sensor.
• At high ambient temperatures, the built-in safety circuit may activate at current input levels below
the rated continuous maximum.

Page 9
• Continuous input of current exceeding the rated maximum or repeated activation of the safety
function may result in damage to the probe.
• The probe is rated for maximum continuous input. Use the probe at RMS current input levels that
are within the rated continuous maximums.The maximum peak input is for a single pulse width of
<10 μs.
• When performing continuous measurements, it is necessary to be aware that the oset voltage
may drift, depending on factors such as the ambient temperature and probe temperature.
• Some sound may be produced by resonance depending on the measured current frequency, but
this resonance has no eect on measurements.
• When carrying out a measurement, press the opening lever until the UNLOCK indication
disappears and check that the sensor head is properly closed. If the sensor head is not properly
closed an inaccurate measurement will be made.
• Accurate measurements may be impossible in locations subject to strong external magnetic elds,
such as transformers and high-current conductors, or in locations subject to strong external electric
or magnetic elds, such as radio transmission equipment.
Operating Method
• Please make sure the current measured doesn’t surpass the maximum rated current of the probe.
If the maximum current exceeds the maximum rated current of the probe the magnetic core will
saturate leading to inaccurate measurements. The T3CP probe will need degaussing and zero set
again.
• When power is rst connected an oset might be present. The T3CP probe normally requires a 30
minute warm up time to stabilize the oset. If an oset is present allow the probe 30 minutes to
warm up then degauss and set zero.
• If the T3CP probe surrounding temperature changes then check the zero setting of the probe and
reset if necessary.
• The position of the conductor under test in the probe measurement jaw will inuence the result. For
highest accuracy results try to keep the conductor under test into the center of the measurement
jaw.
• To make a measurement push the lock / unlock switch all the way until the unlock marker
disappears. Please make sure the switch is locked and the measurement jaw is closed. If the
measurement jaw isn’t closed, the measurements will be inaccurate.
• If measuring the high voltage side of a circuit containing high frequency noise components, the
measurement result might be inuenced by the high frequency noise components. Consider using
the oscilloscopes’ bandwidth limit to reduce the high frequency noise, or consider measuring the
low voltage side of the circuit.
• The continuous maximum input current range will change according to the frequency of the current
under test. The probe will be damaged when operating beyond its specied range at any particular
frequency. Please consult the T3CP probe derating curves in the specications to see the
maximum current at any particular frequency.

Page 10
• When the input current continuously surpasses the maximum input range, the probe sensor self-
protection will be activated. Please discontinue the measurement and allow the T3CP probe to cool
before making another measurement. Degauss and check the zero level after the probe has cooled
and before resuming measurements.
• The sensor protection circuit may be activated by high temperature even when the continuous
current under test is below the maximum specied input.
• When the measured current input surpasses the maximum input current range too often, the
current probe may be damaged.
• When opening the sensor head of the probe, be sure to open it with the opening lever. If the jaw is
forced open when the sensor head is locked, the open / close mechanism and the jaw can be
damaged.
Preparation before testing
• Connect the T3CP current probe to the oscilloscope using the BNC to BNC cable.
• Connect the T3CP probe power supply to the wall socket and connect to the T3CP current probe.
Power up the current probe and the green LED power indicator will light.
• Set-up the oscilloscope: Ground the oscilloscope measuring channel, zero any oscilloscope
channel oset and turn the oscilloscope coupling mode to 1MΩ, DC coupled.
• Select the T3CP current probe range according to the current to be measured. The default setting
of the T3CP probe is to select the larger current setting.
Degaussing and Zero setting
• Connect the T3CP current probe to the oscilloscope (make sure the input impedance of the
oscilloscope is set to 1MΩ, DC coupled).
• Ensure that the probe measurement jaw is empty and lock the probe jaw closed.
• Press the button to degauss and set the probe to zero. The probe will be beep as an indication of
successfully degaussing and zeroing of the probe.

Measuring method
• Unlock the T3CP current probe jaw. Open the jaw and insert the cable to be measured noting the
current direction indicator on the T3CP probe jaw in accordance with the direction of the current to
be measured. Insert the conductor under test in the middle of the measurement jaw.
• Close and lock the T3CP current probe measurement jaw. Observe the waveform under test on
the oscilloscope screen. Adjust the oscilloscope sensitivity settings for the best waveform. Utilize
the current transfer ratio (oscilloscope input scaling) to transform the measured voltage from the
T3CP current probe into an accurate current measurement.
• Change the oscilloscope Y axis from V(olts) to A(mps) if your oscilloscope supports this
functionality.
Frequently Asked Questions and Tips
• Will the T3CP current probes work with oscilloscopes from brands other than Teledyne LeCroy and
Teledyne Test Tools?
The T3CP current probes will work with any oscilloscope that has a BNC input connector and a DC
coupled 1MΩ input. The T3CP probe is powered by a standard wall socket power adaptor that is
independent of the oscilloscope power.
• Can the T3CP current probes measure small currents?
Yes. Each current probe in the T3CP range supports a dual range capability. The default power-on
setting is for the less sensitive range to be selected (the higher range), but the control box allows
the probe to be switched to a more sensitive range for lower current applications. The ranges for
each current probe, and the minimum measurable current is detailed in the specications. When
measuring small currents, ensure that you accurately zero set and degauss the probe, and do not
change the position of the probe hand grip. To observe the smallest most sensitive current
waveforms please set the oscilloscope channel bandwidth lter to 20MHz to eliminate interference
and noise. When measuring extremely small current (a few mA for example), one could make a few
loops of the measurement cable through the probe measurement jaw and divide the result by the
number of loops to obtain the actual current value.
• The T3CP is making inaccurate measurements, what can the problem be?
Check that the oscilloscope is set to 1MΩ input impedance. Check that the oscilloscope’s input
channel is set to DC coupling and that the correct multiplication ratio is entered into the
oscilloscope. Degauss and auto zero the probe. Ground the scope channel and ensure that there is
no oset. Ensure that the lever on the probe jaw is in the locked position when making a
measurement.
• When making measurements please do not let the measurement current exceed the value shown
by the maximum current input rating curve verses frequency. If the max continuous current is
greater than the rating curve verses frequency value then the probe may be damaged.
• To measure accurately, please degauss and zero set the probe, and make sure the probe jaw is
locked during the measurement process.
• Always set the input impedance of the oscilloscope to 1MΩ.

Page 12
• Make sure the probe jaw is locked during testing.
• If possible the probe should be located away from any interference sources such as a transformer
or other magnetic devices. The method to judge if the probe is picking up interference is to put the
probe close to the circuit under test. IF there’s any output, there could be interference in the testing
environment because the probe is connected to the circuit yet. Please always maintain your probe
and do not use it in the humid environment.
• If there’s anything wrong with the probe, please contact Teledyne LeCroy repair. A user should not
dismantle the probe since this will invalidate the warranty.
Care and Maintenance
Cleaning
The exterior of the probe and cable should be cleaned only using a soft cloth moistened with water or
isopropyl alcohol. The use of abrasive agent, strong detergents or other solvents may damage the
probe.
Caution: The probe case is not sealed and should never be immersed in any uid.
