Chapter 7 - ‘Test Conditions’ for help with selecting the tests and test signal conditions that you need.
AND:
The tester’s measure mode can also be used to determine the nominal values of a new part. See section 3.9 of this chapter.

3.4.1 Continuity

The continuity test can be placed as the first test in the program to check that the transformer has been inserted correctly into the test fixture. The test checks that every winding has a resistance less than a user specified limit, the same limit being applied to all windings.

The CTY test is an alternative to using an R (Winding Resistance) test on each winding separately. The CTY test has the advantage of speed of execution; but with the R test, individual limits can be applied to each winding, to give confidence, for example, that the correct wire gauge has been used.

On selecting ‘CTY - Continuity’ from the available tests window, the following dialogue box will be displayed:

To program the test:

  1. Enter the maximum resistance limit.
    Remember that there is only one limit, and the same value will be applied to all windings.
    If all the windings on your transformer have small resistance values, then choose the value of 10kΩ, to give the quickest test execution.
    If any winding has a resistance greater than 10kΩ, then choose a value bigger than that expected for the winding with the largest resistance.
  2. Select OK. The test specification will then be displayed in the program window.
