Selecting a Cable Type Characteristics for a variety of LAN cables are designed into the test too and can be accessed through SETUP. See Table 3. 6 CableMeter Preparing the Test Tool for Use Note Cables not wired according to the predefined cable list cause the test tool to detect failures. However, the test tool will determine the cable's length and display the actual cable wiring with the wire map function. It may be possible to use the test function by making an adapter that causes the cable to appear to be properly wired to the test tool. To set up the test tool for the desired cable, perform the following: 5. Press C or D until the desired wire size is displayed. Note You can check the cable selection at any time other than during the setup mode by pressing the E key. The cable characteristics are now defined by the factory settings for the cable selected. However, cables coming from different batches or manufacturers can have characteristic variances of up to 20 %, causing deviations in length measurements. To obtain more accurate measurements, calibrate the test tool to the specific cable under test. Note The number of steps necessary to select a cable definition will depend on the type of cable selected. 1. Press Cor D until the desired wiring standard is displayed, then press E. Calibrating the Test Tool to the Cable When calibrating the test tool to a specific cable, the cable should be at least 100 feet (30 m) long and of the same type and category as the cable under test. Calibrating with cables longer than 100 feet (30 m) will improve length measurement accuracy. During the calibration process, if the cable is found to be defective or if the cable is less than 50 feet (15 m), "BAD CABLE" is displayed and the calibration process is terminated. 7 620 Users Manual Caution For proper calibration, connect the cable under test directly to the test tool, not through a patch cable. Caution To ensure accurate measurements, make sure conductive objects, including fingers, do not come in contact with any of the connectors while the test tool is measuring the cable under test. To calibrate the test tool to the currently selected cable, perform the following: 1. Connect a good cable of known length, 100 feet (30 m) or longer, to the appropriate test tool conenctor and turn the rotary switch to TEST, LENGTH, or WIRE MAP. 3. abm04f. eps Note When you select a cable type for which the test tool has already been calibration, "CAL" will appear in the second line of the display. To erase this calibration and use the factory settings, remove all cables from the test tool, press D D until "YES" is displayed, and press E. Press C D until YES is displayed, and then press E. The test tool takes a few measurements on the attached cable and displays the measured length. Note If you have just completed the cable selection process, the test tool should already be i the calibration setup selection. 2. Press A and then E until the following display appears. abm05f. eps 8 CableMeter Making Tests and Measurements 4. Press C D until the known cable length is displayed, and then press E. These cable parameters are stored and will remain in memory even if the test tool is turned off. All future measurements for this cable type are compared to these new parameters until another cable is selected or another calibration is performed. Active Pin Connections DB-9 Line Name Data Connector Color Red Green Black Orange 8-Pin RJ45 1 6 5 9 RX+ RXTXTX+ 4 5 3 6 Making Tests and Measurements The test tool displays test results in relation to individual pin numbers. For example, in the LENGTH mode, the following display indicates the twisted pari connected to pins 1 and 2 is 301 feet long whilc the pair connected to pins 3 and 6 is 300 feet long. Note When you test STP cables, the IBM Data Connector in the STP Adapter Kit or AMP part number 555414-2 must be used with the Cable ID Unit. abm06f. eps Testing Cables The TEST function teststhe attached cable and indicates PASS or FAIL based on hte cable's compliance with the parameters stored in the test tool for the selected cable. [. . . ] After installing the Cable ID Unit, press E to continue the self-test program. abm43f. eps The test tool displays PASS or FAIL. The self-test continually repeats until A is pressed or the test tool turns itself off (Battery Save Mode). If any failure is detected, return the unit to a service center for repair. A more thorough self-test can be performed by using the following self-test procedure: 1. With the test tool off, press and hold A while turning the rotary switch to TEST. [. . . ]
