3.4.23 OUT - Output To User Port
The User Port on the AT3600 has 6 ‘Relay Driver’ outputs associated with it. The OUT test allows programming of the User Port relay driver outputs to perform additional relay switching as part of the test program.
An example of this would be an application where a transformer has two separate primary windings. An OUT test could be used to connect them in series, allowing them to be tested as a single primary with twice the working voltage.
A second example is the switching of additional resistors mounted on the test fixture allowing tests to be included in a program on a transformer with a loaded secondary winding.
Each of the relay driver outputs can be set to on or off (closed or open respectively) as shown:
Once the settings are correct click on OK to accept them.
The relay drivers are only set as and when the tester encounters an OUT test. The settings given will remain in place until another OUT test is encountered. Therefore if the settings are required for one part of the test program only, two OUT tests will be required, the first to turn the appropriate relay drivers on and the second to turn them back off.
See the Specification for details of the relay driver configuration.
