See pages 12 through 15. P The W Indicates a fault or high voltage on the cable. SPLIT appears when the fault is a split pair. See page 15. Changing the Length Units 1 Hold down Y and E while turning on the tester. 2 Press M to switch between meters and feet. 3 Turn the tester off then on to return to testing mode.
MicroScanner2 Cable Verifier Users Manual Using the Wiremap Adapter and Remote ID Locators Terminating twisted pair cabling with the standard wiremap adapter or optional remote ID locators lets the tester detect all types of wiremap faults. Without this termination, the tester cannot detect crossed wires or crossed pairs. For a wire pair with one wire open, termination is required to detect which wire is open. Without termination, the tester shows both wires as open.
Testing Twisted Pair Cabling Testing Twisted Pair Cabling 1 Turn on the tester. If the tester is already on and in coaxial test mode (T), press Y to switch to twisted pair test mode (U). 2 Patch panel Connect the tester and wiremap adapter or ID locator to the cabling as shown in Figures 5 through 17. The test runs continuously until you change modes or turn the tester off.
MicroScanner2 Cable Verifier Users Manual Twisted Pair Test Results The following figures show typical test results for twisted pair cabling. Open on Twisted Pair Cabling Figure 6 shows an open on wire 4. Notes If only one wire in a pair is open and a wiremap adapter or remote ID locator is not connected, both wires are shown as open. The warning icon (W) does not appear if both wires in a pair are open because open pairs are normal for some cabling applications. egk05.
Testing Twisted Pair Cabling Short on Twisted Pair Cabling Crossed Wires Figure 7 shows a short between wires 5 and 6. The shorted wires flash to indicate the fault. The cable length is 75.4 m. Figure 8 shows that wires 3 and 4 are crossed. The the pin numbers flash to indicate the fault. Cable length is 53.9 m. The cable is shielded. Note When there is a short, the far-end adapter and the mapping of the unshorted wires are not shown. Detection of crossed wires requires a far-end adapter.
MicroScanner2 Cable Verifier Users Manual Crossed Pairs Figure 9 shows that pairs 1,2 and 3,6 are crossed. The pin numbers flash to indicate the fault. This crossed pair is likely caused by mixing 568A and 568B cabling. Detection of crossed pairs requires a far-end adapter. egk09.eps Figure 9.
Testing Twisted Pair Cabling Split Pair Figure 10 shows a split pair on 3,6 and 4,5. The split pair flashes to indicate the fault. The cable length is 75.4 m. In a split pair, continuity from end to end is correct, but is made with wires from different pairs. Split pairs cause excessive crosstalk that interferes with network operation. Note Cables with untwisted pairs, such as telephone cords, typically show split pairs due to excessive crosstalk.
MicroScanner2 Cable Verifier Users Manual Telephone Voltages Detected Figure 11 shows that telephone voltage is detected on pair 4,5. Length is not shown because the voltage interferes with length measurements. WWarningX The tester is not intended to be connected to active telephone inputs, systems, or equipment, including ISDN devices. Prolonged exposure to the voltages applied by these interfaces may damage the tester. Telephone voltage icon Positive wire (tip) Negative wire (ring) egk11.
Testing Twisted Pair Cabling Bridge Tap Detected Figure 12 shows a bridge tap detected at about 53.2 m. Only the first bridge tap detected is reported. The distance to a bridge tap is approximate because multiple reflections from the bridge tap interfere with length measurements. Note Bridge taps more than 328 ft (100 m) from the tester or taps less than 16 ft (5 m) long may not be detected. egk12.eps Figure 12.
MicroScanner2 Cable Verifier Users Manual Ethernet Port Detected The tester can detect active and inactive Ethernet ports, as shown in Figure 13. A Ethernet port icon. B Port speed for an active 1000 megabit port. The speeds are 10, 100, or 1000 megabits per second. The example shows 1000 megabits per second. If the port supports multiple speeds the number cycles through the speeds. 18 C Cable length. Dashes are shown if the tester cannot measure the length.

For cabling not terminated with an F-connector, use an adapter or hybrid patch cord to connect to the cabling. Connection to service Coaxial patch cords The test runs continuously until you change modes or turn the tester off. Wall outlet Wiremap adapter egk19.
Testing Coaxial Cabling Coaxial Results Open on Coaxial Cabling Figure 19 shows a good coaxial cable 38.4 m long and terminated with remote ID number 3. Figure 20 shows an open 12.1 m from the tester. egk21.eps egk20.eps Figure 20. Open on Coaxial Cabling Figure 19.
MicroScanner2 Cable Verifier Users Manual Short on Coaxial Cabling Unknown Termination on Coaxial Cabling Figure 21 shows a short 12.1 m from the tester. Figure 22 shows a cable connected to a device at the far end, such as a television, CATV service, VCR, DVD player, satellite dish, splitter, or antenna. Dashes shown for length mean the tester cannot measure length because the device does not produce reflections. egk22.eps Figure 21. Short on Coaxial Cabling egk23.eps Figure 22.
Detecting Power Over Ethernet Detecting Power Over Ethernet The tester can detect PoE voltage from 802.3af sources. To select PoE mode, press M until PoE appears on the display, as shown in Figure 23 (A). In PoE mode, the tester solicits PoE power on pairs 1,2-3,6 and 4,5-7,8. The tester may activate a PoE source and will not be damaged by PoE power. If PoE power is detected, Poeappears above the powered pairs (B). The Poemay blink as the PoE source turns the power on and off.
MicroScanner2 Cable Verifier Users Manual Using the Toner You can use the tester with an optional tone probe to locate cables in bundles, at patch panels, or behind walls. Use the tester’s IntelliTone™ mode with an optional Fluke Networks IP100 or IP200 tone probe. The digital IntelliTone signal is easier to detect at a distance than analog tones, and its frequency and encoding eliminate cable misidentification due to signal bleed and radiated or ambient noise.
Using the Toner Notes If you cannot locate the IntelliTone signal on 2-conductor cables, the cable may be shorted. Use the tester to check for shorts. See pages 11 and 13. 7 Turn the probe’s rotary switch to N (isolate). 8 Use the probe to isolate the tone source in the cable bundle or at the patch panel. The SYNC LED lights up green when the probe is receiving the IntelliTone signal. The probe’s LEDs light up from 1 to 8 as the signal strength increases. The higher the number, the stronger the signal.

Using the Toner Analog Toner Mode (optional tone probe required) Refer to Figure 26. 1 Connect the tester to the cable. 2 Press Y to select twisted pair or coaxial cable. 3 Press M until L appears on the display (A); then press D to enter analog toner mode. The display shows a scrolling sinewave in analog toner mode (B). 4 To change songs, press D. The display shows the song number (C). The analog toner has four songs.
MicroScanner2 Cable Verifier Users Manual Using the SmartTone Function Use the SmartTone function when you have trouble locating a cable. This function changes the toner’s song when you short a wire pair in the cable connected to the tester. SmartTone works with the IntelliTone probe and with analog probes.
Using the IntelliTone Cable Map Function (optional IP200 probe required) Note Normally, the probe’s SYNC LED lights to indicate reception of the IntelliTone signal. You may change the LED’s function to indicate shield continuity. See the probe’s documentation for details. LEDs show the wiremap. See the ITK200 manual for details. egk26.eps Figure 27.
MicroScanner2 Cable Verifier Users Manual Calibrating Length Measurements Setting the NVP to a Specified Value The tester uses an NVP value (nominal velocity of propagation) and the signal delay through the cable to calculate length. The tester’s default NVP values are usually accurate enough to verify length; however, you can increase the accuracy of length measurements by adjusting the NVP to a specified or actual value.
Maintenance Notes Maintenance The cable must be at least 49 ft (15 m) long. If the cable is too short, “---” appears for the length. WWarningX To avoid possible fire, electric shock, personal injury, or damage to the tester: For the best accuracy, use a cable between 49 ft (15 m) and 98 ft (30 m) long. The cable must not be connected to anything. 4 To switch between meters and feet, press M. 5 Use E and D to change the NVP until the measured length matches the actual length of the cable.
