  • Tips & Tricks 1 General RemarksThis collection of tips and tricks is intended to address Test Universe novices as well as experienced users.

    Section 2 guides beginners through the first steps with Test Universe .

    More experienced users will find useful hints in the other sections of this collection.

    This way, "Tips & Tricks" supplements the Help (functional description of the Test Universe software) and the manuals (application examples using the individual test modules).

    The bookmarks in the left pane of your PDF reader provide an overview of the available topics.

    2 First Steps with OMICRON Test UniverseTest Universe (TU) is the software suite for setup, execution and administration of secondary system testing (e.g., relay testing) by means of one or several test sets such as CMC 256 that generate the test signals and analyze the reaction of the device under test.

    These hints are intended for users not yet familiar with the general concept of Test Universe. Please also have a look at the Tutorials (see entry on Start Page, via installation from DVD) that give a live demonstration of some aspects of Test Universe.

    2.1 Start PageThe OMICRON Start Page is the central navigation interface when launching Test Universe. Its tools cover all aspects from simple test shots to complex and/or automated test sequences as well as the maintenance of test setups and results.

    The Test Modules section allows the individual launching of modules for diverse test purposes, from generic ("virtual front panel") QuickCMC over general (Ramping, State Sequencer) and dedicated (Overcurrent) to network simulation.5

  • OMICRON Test UniverseCB Configuration controls the parameters of a process that may run in parallel to ongoing tests. It simulates the behavior of a circuit breaker (timing of position contacts 52a and 52b as resulting from Open or Close commands) using binary inputs and outputs of the connected CMC.

    The Control Center section allows the bundling of individual modules (as those listed in the Test Modules section) to form complex test sequences. Besides arranging modules as needed in a so-called Control Center Document (*.occ file) from New Test Document you may directly use predefined test arrangements defined for specific relay types using Open Protection Library. These OCCs are open to further alterations as needed. This library is updated on a regular basis, announced on the Web site and in the OMICRON News window (see above).

    The Test Administration section gives access to TestBase, a powerful test administration software that can be ordered for free via the OMICRON Web site Customer Area. Separate help for this tool is available from its user interface.

    The Test Tools section contains further test-related applications that are to be used in a stand-alone fashion as opposed to the modules under Test Modules that can be included in Control Center documents. AuxDC allows setting the voltage of the AuxDC output of adequately equipped devices (e.g. CMC 256).

    In the Setup section you find all means to set up your working environment. With the Test Set Association component you associate and configure your OMICRON CMC test set(s) via Ethernet. Using the Ethernet interface, you can put as many CMC test sets as you wish on the network and control them by even geographically remote computers (clients). System Settings provides the means for system-wide default settings. The License Manager combines the functionality of a license browser, a merge tool and a license file editor. It searches for OMICRON license files stored on the computer's hard disk(s) and displays their contents. It merges license information from different files into the master license file Omicron.lic. It furthermore allows to add license keys manually. And Language Selection lets you change default language for the Test Universe user interface.

    The Support section offers access to the Help (describing the handling of the software tools), the manuals (describing typical applications with examples), OMICRON Assist for troubleshooting support, and more.

    The Custom section might contain pre-configured entries for certain customers, and is open for your own add-ons of external programs that you would like to launch from this location. If interested please click the User-specific Tools link to learn how this can be done.6

  • Tips & Tricks The header area contains links to OMICRON Web sites. Furthermore, if your computer has access to the Internet and when an update to your current TU software version is available, a related link will be shown underneath the version indication allowing you to directly look up the related information on the Web site.

    But now some first steps for actual testing:7

  • OMICRON Test Universe2.2 Basic "Front Panel" Testing: QuickCMCLaunch QuickCMC, the first entry under Test Modules. The module starts in Direct Set mode, i.e., you can directly define the currents and voltages per output. In other set modes you may define the quantities, e.g., as fault impedance. Via the V I E W menu (or the related toolbar icons) you may display an additional Vector view (allowing the representation of the electrical quantities in various ways,
