Performance Verification
This procedure can be used to verify the warranted characteristics of the CP150 Current Probe.
The recommended calibration interval for the model CP150 Current Probe is one year. The complete
performance verification procedure should be performed as the first step of annual calibration.
Performance verification can be completed without removing the probe covers or exposing the user to
hazardous voltages. Test results can be recorded on a photocopy of the Test Record provided at the end
of the manual.
Adjustment should only be attempted if a parameter measured in the Performance Verification
Procedure is outside 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 his procedure.
NOTE: The correct operation of the CP150 controls requires software version 4.3.0.0 or higher. The
software version in the test oscilloscope can be verified by selecting Utilities > Utilities Setup > 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
