14.5.11.
When measuring small values of resistance, inductance or capacitance, the
effects of the fixture can add significant errors to the results. To allow you to
make more accurate measurements, the AT Series Testers have built-in firmware
to compensate for the fixture effects.
From the top-level menu bar, select Tester > Compensate Fixture;
If your program does not contain any tests where compensation can be applied,
you will see the following message:
When you click on 'OK' to return to the top-level menu, the tester will not make
any measurements.
Most programs will contain at least one test where compensation can be applied.
In this case, you will then see one of two messages:
At this point you should ensure that the appropriate fixture has been placed on the
tester. With the first message, it is possible to leave the fixture empty.
The second message will be displayed when the program contains at least one
test for which short-circuit compensation is applicable. As the program may also
contain tests requiring open-circuit compensation, you should ideally plug a
dummy header into the fixture, where all the transformer windings are replaced by
short-circuit links.
After you have clicked on the 'OK' button at either of the messages, the tester will
be commanded to make the compensation measurements for your test program.
