  • Page 7: Introduction To The Cirris 1000Hn

    Cirris 1000HN Lets get started! The Cirris 1000HN cable analyzer is an easy-to-use machine that will allow you to test cables quickly, and with little fuss. In simple terms, the process of using your 1000HN goes like this: Install an expansion box if you want to use one (see page 10 for details).

  • Page 9: Section 1: Work With The Hardware

    Work With the Hardware The Cirris 1000HN system consists of a main unit, and an optional expansion box. To connect the cables you want to test to the analyzer, you use connector adapters which match the connectors on the cable you want to test.
  • Page 10 Section 1: Work With the Hardware / How to install an expansion box Replace the cover plate, making sure the small alignment pins on its underside fit into the corresponding holes on the scanner’s upper surface. Each cover plate alignment pin..fits into a hole in the scanner’s upper surface.

You also see the plastic plate in the main unit’s cable routing opening partially removed. You should remove the plate completely. Make sure the connections to both the main unit’s scanner and the scanner in the expansion box are secure.

  • Page 19: Section 3: What The Option Settings Mean

    Option Settings Mean Overview The Cirris 1000HN has eleven test option settings which you set to meet your testing requirements. In this section, we’ll tell you what each of the settings means. Create Test From Gives you the option to create a new test setup from a new Sample Cable, your last test setup, or by learning a complex cable that contains resistors and/or diodes in addi- tion to ordinary wire connections.
  • Page 20 Section 3: What the Option Settings Mean / Insulation Resistance mines how effective the insulation on a cable is during a test. The higher the voltage you set, the higher the insulation resistance the analyzer can detect. Voltage settings will affect the range of insulation resistance settings available to you. Warning!! Do not subject cable assemblies to voltages higher than they are designed to handle, because this may damage them.

  • Page 30 Section 5: Test Your First Cable / Print or transcribe an error list Passed Hipot Test If the hipot test is successful, the analyzer briefly prompts Passed Hipot Test, then cycles to a continuous resistance test and prompts Good R<.XΩ. The analyzer emits a steady clicking sound after each newly-completed continuity/conductance test.

  • Page 31: Section 6: Retrieve A Cable From Memory

    Section 6: Retrieve a Cable from Memory Why retrieve a cable? Before the 1000HN 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).

    Section 8: Print a Directory of Cables Stored in Memory Overview If you have a printer connected to your 1000HN, 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 36 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.

For example, if you intend to use adapter positions J2 and J4, first install the connector adapter at position J2.

  • Page 43: Section 10: Select A Test Procedure

    Section 10: Select a Test Procedure Types of Tests Using the Cirris 1000HN, you can perform two different kinds of tests. These are: Simple tests. Hipot tests. Simple Tests Simple tests are used for testing cables made up of only wires and connectors. These cables have no resistors, capacitors, diodes, or any active circuitry.
  • Page 44 Section 10: Select a Test Procedure / Hipot Testing Typical test 0.5Ω 100MΩ 300V 100mS Use these settings when low connection resistance is important, and the cable has little capacitance. Low connection resistance may require careful adapter maintenance. The hipot test will not work on extremely long cables.
