Instruction Manual

Adjustment Procedure
This procedure can be used to adjust the warranted characteristics of the CP150 Current Probe. This
procedure should be used if a parameter measured in the Performance Verification Procedure is outside
of the specification limits. Adjustment should only be performed by qualified personnel.
The warranted characteristics of the CP150 Current Probe are valid at any temperature within the
Environmental Characteristics listed in the Specifications. However, some of the other test equipment
used to verify the performance may have environmental limitations required to meet the accuracy
needed for the procedure. Make sure that the ambient conditions meet the requirements of all the test
instruments used in this procedure.
NOTE: The correct operation of the controls of the CP150 requires oscilloscope software version 4.3.0.0
or higher. The software version in the test oscilloscope can be verified by selecting Utilities, Utilities
Setup, then the Status tab. Contact your local Teledyne Lecroy representative if the software in your
oscilloscope requires updating.
Test Equipment Required
The following table lists the test equipment and accessories, or their equivalents, which are required for
adjustment of the CP150 Current Probe.
Because the input and output connector types may vary on different brands and models of test
instruments, additional adapters or cables may be required.
