Fluke - 26500390 - Fault locator & Tone Generator
Model No :
Part Code :


The TS 100 cable fault locator lets you easily find the distance to opens or shorts on electrical wire, telephone wire, security wire and coax. Results appear as a distance reading rather than a waveform, so it's perfect for technicians unfamiliar with Time Domain Reflectometery (TDR) fault locator.

- Three tools in one — a fault locator, cable and wire manager, patented SmartTone™ analog tone generator
- Instantly measures distance to open or any fault from one end of any cable pair
- Tone generator positively identifies pair
- High voltage detection
- Moisture proof
- Large LED screen and easy-to-use menu

General Specifications
- Power 4 AA alkaline batteries provide 50 hours “on” time. (Approx. 1 year, normal use). 5 minute auto-off if unit is not connected; 1 hour auto-off when connected. No damage if batteries are installed backwards
- Input protection 250 V RMS AC, Continuous or Intermittent
- Moisture If exposed to water, TS 90 and TS100 will suffer no damage. See moisture notes in Notices section of manual
- Impedance range Auto-compensation within 25 to 330 ohms
- Cables with an impedance outside this range may produce erratic or incorrect readings
- Maximum length The unit will display “-LL-” if the cable is too long to be correctly measured
- Maximum cable testing length 2,500 feet for the TS90, 3000 feet for the TS100 (can test longer on certain cables)
- Minimum length No minimum length. Minimum non-zero reading is 1 foot
- High voltage detection AC voltage > 5 to 15 Volts RMS will trigger High Voltage Warning
- Measurement rate Maximum of 4 complete measurements/second, decreasing to 2 seconds per measurement. Based on cable size and uniformity
- Measurement technology Time Domain Reflectometry (TDR) with 50 ohm drive impedance, 6 V maximum pulse height. (Patents Pending)
- Tone injection Approximately 1 kHz at an amplitude of 80% battery voltage. Variable frequency and cadence
- Tone changes when cable condition changes to “normal-open” from any other condition
- Cable type Virtually all two or more conductor cables
- Temperature 0º to 55º C operating; 0º to 70º C storage
- Dimensions 7.4” tall x 1.5” thick x 2.75” wide
