TCP303 and TCP404XL Adjustments
Each of the following adjustment procedures describes how to adjust specific
performance characteristics of the TCP303 and TCP404XL. Tolerances that are
specified in these procedures apply to the current probe and do not include test
equipment error.
Required Test Equipment
To perform the adjustment procedures in this section, you will need the test
equipment listed in Table 6--8. The test equipment must meet or exceed the
specifications listed. You may need to modify the test procedures if you do not
use the recommended equipment.
Perform the steps on page 6--1 before starting these procedures. To ensure proper
completion, read each procedure before starting.
