condition. Follow generally accepted safety procedures in addition to the precautions
specified in this section. The overall safety of any system incorporating this product
is the responsibility of the assembler of the system.
Symbols
These symbols appear on the product or in its documentation to alert you to
important safety considerations.
CAUTION of potential damage to product, or WARNING of potential bodily
injury. Refer to the manual to protect against injury or damage. Do not
proceed until conditions are fully understood and met.
Precautions
Use only as intended. The product is intended to be used only with the compatible
Teledyne LeCroy instruments. Using the product and/or the equipment it is connected
to in a manner other than specified may impair the protection mechanisms.
Do not apply a voltage to any input that exceeds the maximum rating of that input.
Refer to the body of the oscilloscope and the product page at teledynelecroy.com for
detailed information.
Use indoors only. The accessory is intended for indoor use and should be operated in
a clean, dry, environment. Do not use in wet/damp or explosive atmospheres.

Introduction
The CA10 ProBus Current Adapter allows current transducers and transformers that
output a voltage or current signal proportional to a measured current to be easily
connected to an oscilloscope or motor drive analyzer. Specific information about the
input device is programmed into the CA10 so that when the device is connected to
the instrument it will correct for the transducer/transformer gain or attenuation and
display the result in Ampere units.
Using the CA10 with transducers/transformers saves the time (and errors) involved
in manually entering scaling factors and units each time the device is connected to
the instrument.
CAUTION. The secondary of a current transformer (CT), when unterminated,
can generate hazardous open-circuit voltages when energized. These
voltages could be dangerous to personnel and damage the oscilloscope. If the
CA10 is used with an unterminated current transformer, you must install a
suitably rated terminating resistor in the CA10 before energizing the CT. See
Customizing the CA10 for details.

Connecting the CA10
Using the Heat-Shrink Tubing
We highly recommend using the included heat-shrink tubing to semi-permanently
attach the CA10 to the transducer/transformer for which it has been programmed.
However, the heat-shrink tubing is not required, and the CA10 will function perfectly
without it.
Cut the tubing into 1.5" length sleeves before using.
Connecting the CA10 to the Transducer/Transformer
1. Slip one of the sleeves over the transducer/transformer's BNC output connector.
2. Connect the device to the CA10 BNC input connector.

Operator's Manual
3. Slide up the sleeve so that it is flush to the body of the CA10 and completely
covers the connector. Apply heat until the wrap snugly encases the connection.
4. If desired, attach a removable label the front of the CA10 case and write the
name and/or setup of the attached device.
5. Connect the CA10 to a ProBus input on the instrument.

Programming the CA10
When the CA10 is first connected to the instrument, you will be asked if you want to
program it. Select Yes to display the CA10 dialog:
Enter all the device settings on the dialog, then select Save to Adapter.
In the future, the CA10 will update channel settings automatically as long as there is a
program saved on it. The CA10 dialog will appear behind the input channel dialog
whenever it is connected to the instrument, with the sensor name appearing next to
the channel number on the tab.
To change the programming, open the CA10 dialog, then select Edit before modifying
the settings. Use Clear to quickly clear the previous settings. These buttons are only
active after a program has been saved.
Remember to Save to Adapter after reprogramming.
