While working through the Quick Start Tutorial (section 3, chapter 2), you may have
noticed that the dialogue box for the test R - Winding Resistance - contained a button
labeled 'Measure'.
In fact, most tests have a Measure button within the dialogue box. It is included there
to allow you to fill in various fields in the dialogue box by using the AT3600 to
measure the value from a sample transformer.
All tests with a Measure button will allow you to enter a value into the test limits
section of the dialogue box.
In addition, some tests can also make use of the Measure button to select the test
conditions. The programming details for each test in section 4 (Programming Tests)
later in this chapter, specify which tests allow the Measure button to enter the test
parameter values.

Before attempting to use the Measure button:
WARNING: If the chosen 'COM' port is reserved by another Windows
i
application, an error message will appear. You should select another port.

AGE
This is because the Editor only holds the latest limit values, and therefore when
you have changed to a minimum only limit, any previous maximum value will be
lost.
(such as > < ), the conversion process has in essence to use the previous
single value as both the minimum and maximum new values.
As it is not logical to have a minimum and a maximum exactly the same, the two
values are made different, but only by a small amount.
