    Operation Turning on the Tester Turn the tester on by pressing the ON/STANDBY button. The tester performs a self test each time it is turned on. During the self test, the tester displays 8.8.8.8. Automatic Power-Down To save battery power, the tester automatically turns off after five minutes if it is not connected to anything, or one hour after you connect to a cable.

  • Page 13 Operation To use the SmartTone System: Connect the tester to a wire pair; then turn on the tester. At the other end of the cable, use your tone probe to find the wire pair by probing for the pair with the loudest tone.

  • Page 14: Velocity Of Propagation (Vop)

    TS90 Cable Fault Finder Users Guide Velocity of Propagation (VOP) VOP is a cable specification indicating the speed at which a signal travels down the cable. A VOP of 66 means the signal travels at 66 % of the speed of light. The tester uses VOP to calculate cable length.
  • Page 15 Operation To determine the VOP of a known length of cable: Connect a known length of cable to the tester. The cable must be 200 feet (60 meters) or longer (such as an unopened box of wire). Turn the tester on while holding down the UP or DOWN button.

  • Page 16: Applications

    TS90 Cable Fault Finder Users Guide Applications See Figure 3. The tester locates opens, short circuits, and crosses in any two metallic conductors (twisted, untwisted, coax, copper, aluminum, and steel). It identifies conductors using the SmartTone feature and an inductive probe (not included) (see Figure 2). Tone can be sent between two technicians to ID multiple pairs.

  • Page 18: Testing Wire In Conduit

    TS90 Cable Fault Finder Users Guide Testing Wire in Conduit There are two methods for testing wire in conduit. You can test a wire pair or a single wire. Testing a Wire Pair in a Conduit To test a wire pair, connect the two test leads to the pair. If one wire separates from the other for 1 ft or more, the tester indicates an open at the separation.
  • Page 19 Applications At the job-site, you can determine if the cable remaining on your spool or in your box will be sufficient for the job at hand. This will save you an unnecessary trip to the warehouse for more cable, and help you avoid running out of cable in the middle of an installation.

  • Page 23: In Case Of Unstable Or Unusual Readings

    Time Domain Reflectometry (TDR) Technology In Case of Unstable or Unusual Readings Sometimes, devices connected to the cable you are testing can prevent the TS90 from making a valid reading. Such devices include telephones, fax machines, modems, speakers, transformers, light bulbs, televisions, and dc loads. The software makes the best decisions it can when faced with unusual conditions, but may not always be able to ignore connected devices.
  • Page 24 TS90 Cable Fault Finder Users Guide For example, if one or both wires of the pair are broken (open), or they are shorted to each other, or they become sufficiently separated from each other, their impedance will change. The tester looks for these changes in impedance. If the impedance change is large enough, (e.g., such as that caused by a break in one of the wires of the pair), the tester will detect the impedance change and will display the length...
  • Page 25 Time Domain Reflectometry (TDR) Technology TDR technology examines this TDR waveform (see Figure 4), looking at the sizes of the flat sections and the bumps. The software decides which of the elements of the waveform is most representative of the common problems encountered in the wiring industries and reports the distance to that element.

  • Page 26: Vop Variations

    TS90 Cable Fault Finder Users Guide The actual formula used is as follows: Time in billionths of a second  --------------------------------------------------------------------------------- - ----------------- - Length 0.9835 The time is divided by two because the signal traveled the length of the cable twice. Once when it left the tester and went to the failure point, and again when it reflected back to the tester to be detected.

  • Page 27: Maximum Length

    Time Domain Reflectometry (TDR) Technology Depending on the cable construction (shielded, twisted, etc.), insulating material (foam, air, fiber, etc.), and conductors tested (wire-to-wire, wire-to-shield), coiling the cable on a spool or in a box may alter its VOP. Additionally, other conductors in close proximity to the conductors being tested can affect the VOP.

  • Page 28: Frequently Asked Questions

    TS90 Cable Fault Finder Users Guide Frequently Asked Questions Q: How do I calibrate the tester or perform a self test? A: There are no adjustments inside the tester, and the internal coating protects the critical components from moisture and contaminants. There is nothing to calibrate. A self test is performed by the tester every time you turn it on.
  • Page 29 Frequently Asked Questions A: No. The accuracy of the reading is dependent on the setting of the VOP. While the nominal setting for general testing is -66-, the VOP for that kind of cable is -56-. To improve the accuracy of length measurements for that or any cable, change the VOP as shown in the instructions in the Velocity of Propagation section.
  • Page 30 TS90 Cable Fault Finder Users Guide Q: I accidentally cracked the plastic housing, does this affect the moisture protection of the components? A: Not at all. The component protection is provided by a coating on the components and Printed Circuit Board (PCB). However, if sufficient plastic is missing then a possible shock hazard exists.
  • Page 31 Frequently Asked Questions Q: When testing a set of wires that go into a conduit, I sometimes get a reading of 0 or 1. Why? A: If there is more than a foot or so of wires that are physically separated before they enter the close confinement of the conduit, this will look to the tester like an open at the start of the cable.

  • Page 32: If Something Seems Wrong With The Tester

    TS90 Cable Fault Finder Users Guide If Something Seems Wrong with the Tester The display remains at 8.8.8.8. after power on. The self test has failed. The batteries may be weak or the tester has water inside. Try changing the batteries or drying the tester.
