Select a new object from a list.
Select the desired object from the list with the ↑↓ keys and
acknowledge with the ↵ key.
Depending upon the profile selected in the test instrument’s
SETUP menu (see section 4.5), the number of object types may
be limited, and the hierarchy may be laid out differently.
Enter a designation.
Enter a designation and then acknowledge it by pressing ✓.
Note
Acknowledge the standard or adjusted parameters
shown below, because the created designation will oth-
erwise not be accepted and saved.
Set Electrical Circuit Parameters
For example, nominal current values must be entered here for the
selected electrical circuit. Measuring parameters which have been
accepted and saved in this way are subsequently accepted by
the current measuring menu automatically when the display is
switched from the structure view to measurement.
Note
Electrical circuit parameters changed during structure
creation are also retained for individual measurements
(measurement without saving data).
If you change the electrical circuit parameter specified by the
structure in the test instrument, a warning is displayed when
the change is saved (see error message on page 48).
14.3.2 Searching for Structure Elements
Regardless of the currently selected object, the search is started
at database.
