  • Page 28: Section 6: Retrieve A Cable From Memory

    Section 6: Retrieve a Cable from Memory Why retrieve a cable? Before the 1000R+ can test cables, it has to be programmed with wirelist data for the cables you intend to test. You can avoid having to re-learn a Sample Cable each time you want to test, by storing the learned information in the analyzer’s memory (see page 24 for instructions on how to do this).

  • Page 30: Section 7: Delete A Cable From Memory

    Memory Why delete a cable? The Cirris 1000R+ has a maximum of 50 permanent memory locations for storing cable information. How many locations are actually available depends on the size of the wirelists being stored. Small wirelists take up less space than large ones. You may need to delete cables to make room for new wirelists, or to discard wirelists you no longer use for testing.
  • Page 31 Section 7: Delete a Cable from Memory / How to delete a cable Memory Function Continue to hold in the button while you press to select the Function cable for deletion. Continue to hold down the switch as you do the next step.

    Section 8: Print a Directory of Cables Stored in Memory Overview If you have a printer connected to your 1000R+, you can print a directory that shows all the Sample Cables stored in the analyzer’s memory. The directory will show the memory location number, and the signature of the Sample Cable stored in each mem- ory location.
  • Page 33 Section 8: Print a Directory of Cables Stored in Memory / Print out a directory Function When the display prompts Press Function To Print Dir, press the switch. If your printer is properly connected to the analyzer, turned on, and on- line (selected), it will print a directory showing the signatures of all the cables stored in memory, and their corresponding location numbers.
