    This easy-to-use, competitively-priced tester has three tools in one—a fault locator, a cable and wire manager, and a tone generator with SmartTone technology. From just ONE END of any two or more conductor cables, you can measure up to 2,500 feet (762 meters). Easily find the distance to open or short 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 Reflectometer (TDR). Find and fix cable problems without pulling new wires or blindly cutting into walls. Intermittent faults are easier to find because the unit constantly measures while "On."

    It's perfect for inventory management of cable stock in trucks and warehouses and it can help you generate more accurate bids for jobs by quickly assessing needs and managing the cable stock with greater accuracy.

    Patented SmartTone technology gives you five distinct tones to use for exact wire and pair identification, even in proximity to current-bearing cable. When touching the wires together and momentarily shorting the far end of a cable pair, the SmartTone technology will change the cadence of the tone generated.  This tone change you hear through a probe positively verifies the correct wire pair.

    Voltage detection in the unit will immediately sound an alarm if you accidentally clip onto an energized pair, up to 250VAC.

General Specifications 
Power of operation4 AA alkaline batteries, provide 50 hours
  
Reverse Battery ProtectionNo damage to the tester will occur if the batteries are installed backward.
  
Input Protection250 V rms ac, continuous or intermittent
  
MoistureIf the tester is exposed to water, some may get inside, but it will suffer NO DAMAGE. See the moisture notes in the Maintenance section.
  
Impedance Range35 Ω to 330 Ω with auto-compensation within this range. Cables with an impedance outside this range will not be properly tested and may produce erratic or incorrect readings.
  
Maximum Length2500 feet on most cable types, and 500 feet on very lossy cables. The tester will feet on very lossy cables. The tester will display –Err if the cable is too long to be correctly measured.
  
Representative Maximum2500 feet: CAT-5 Twisted Pair
Cable Length2000 feet: 12/2 ac Wire
 1000 feet: RG-6/U TV Coax
 500 feet (150 meters): RG-174/U Coax
  
Minimum LengthNo minimum length. The minimum non-zero reading is 2 feet.
  
Length Accuracy±2 feet for cables less than 10 feet ±5 feet for cables longer than 10 feet and shorter than 200 feet ±3 % and ±5 feet for cables longer than 200 feet
  
High Voltage DetectionAn ac voltage of more than 5 V rms will trigger the High Voltage Warning.
  
Measurement RateMaximum of 4 complete measurements per second, decreasing to 2 seconds per measurement based on cable size and uniformity.
  
VOPAdjustable from -20- to -99-, retained during power off. Default to -66- when batteries are changed.
  
Measurement TechnologyTime Domain Reflectometry (TDR) with 50 Ω drive impedance, 6 V maximum pulse height.
  
Low BatteryThe indicator flashes when the battery voltage falls below 4.1 V
  
Tone InjectionApproximately 1 kHz at an amplitude of 80 % of battery voltage. Variable frequency and cadence. The tone characteristic is changed as the cable condition changes to “normal-open” from any other condition.
  
Cable TypeVirtually all two or more conductor cables
  
Temperature Range Operating Storage32 °F to 131 °F (0 °C to 55 °C) -40 °F to 158 °F (-40 °C to 70 °C)
  
Humidity Operating Storage0 % to 80 % 0 % to 100 %
  
Weight1 lb with batteries and clip leads
  
Operating Altitude10,000 ft max
