Copper Test 289
17 Test Lead Compensation
Test lead compensation is required for some of the copper tests so as not
to affect data accuracy, since test lead characteristics have some impact on
copper test results (mainly resistance, capacitance, and TDR tests). Test
lead characteristics vary with respect to cable temperature.
The Test Lead Compensation routine allows you to perform resistance
and capacitance compensation. The page displays the Pass/Fail status of
the last compensation done.
Note: For greatest accuracy, perform a test lead compensation before a new test
session with the FTB-1 unit.
To access Test Lead Compensation:
1. From the Copper main menu Test Groups, select Test Lead
Compensation .
2. From the Tests menu, select Test Lead Compensation.
By default, the Test Lead Compensation page opens.
