Each TP can have multiple Test Profiles. Test Profiles can be added/editted via the Testing Tab on the Test Point Add/Edit form. For more details see Test Profiles.
Each TP has at least one test profile as a default profile that cannot be deleted or disabled by the User; this profile is called CON-Default and it is used in the baseline Continuity test.
If the TP is a Nodal Ground, then the CON-Default is automatically disabled.
