Description

The Megger‚ TDR500 cable fault locator breaks new ground as a cost effective high specification hand held Time Domain Reflectometer (TDR) for locating faults on metallic cables.

Designed for the field engineer requiring a low cost solution to field testing, the TDR500 offers all the benefits of Megger build quality and reliability in a high quality affordable package.

Transmission line testing
The TDR500 is suitable for virtually all types of transmission cable including twisted pair, coaxial and parallel conductors. Condition of the entire cable or section is displayed graphically

30m to 3 km Range
Suitable for identifying and locating a range of cable faults from a few metres up to 3 Km on non-energised cables. Cable characteristics are clearly displayed on the 122 x 32 pixel LCD display.

Simple Operation
Operation of the TDR500 is simplicity itself. No multifunction keys to confuse the operator. Each button has its own dedicated function.

Just connect the test lead to the de-energised cable to be tested. Switch on the TDR and set the Velocity factor.

Cable route tracing
The TDR500 can inject an oscillating 810 Hz/1.11 kHz tone onto the de-energised transmission line or power line.

The warble tone allows the engineer to trace the faulty cable pair with the use of a commercially available tone tracing probe.


TDR900

Hand-held Time Domain Reflectometer/Cable Length Meter

  • » Full autoranging for measuring the length of power, telephony, CATV and LAN cables, provides distance to an open or short.
  • » Extra large, high resolution backlit LCD.
  • » Automatic output impedance control of 25, 50, 75, 100, 125 or 150 ohms.
  • » User-friendly menu on screen operation.
  • » Cable length calibration function.
  • » Internal library of 39 standard cable types.

Description

The Megger TDR900 is an advanced instrument capable of measuring cable lengths and finding distance to an open or a short using Time Domain Reflectometry. It offers exceptional features and a range capability normally associated with far more expensive instruments. The measurement range spans from 15 feet (5 m) to 10,000 feet (3 km) with a minimum resolution of 20 inches (50 cm).

The TDR900 can be used for any cable consisting of at least two insulated metallic elements, one of which may be the sheath or shield of the cable. The Meter has automatic internal matching networks to allow testing of 25Ω, 50Ω, 75Ω, 100Ω, 125Ω, or 150Ω cables. (These correspond to power, telephony, CATV, and LAN cables.)

The Meter can be closely matched to the cable under test using the menu selection keys. The propagation velocity value can be similarly adjusted to match the cable under test; thus ensuring an accurate distance measurement. The other user adjustable setting is changing the distance measurement units (feet or meters).

The Meter is housed in a rugged ABS enclosure which is dust and weatherproof to IP 42. The unit also comes with a soft carrying case and an alligator clip adapter. It is powered by 4 AA (NEDA 15A or NR 6) batteries, which are stored in a compartment on the back of the Meter. The batteries are held in a carrier for quick and easy replacement.


TDR1000/2

Cable Fault Locator

  • » Simple operation
  • » Fast fault find facility
  • » TX Null transmission pulse nulling
  • » Adjustable cable impedance
  • » No blocking filter required
  • » IP54 rating
  • » 3 year warranty

Description

The TDR1000/2 is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1m/0.3ft and a 3km/9kft maximum range depending on Velocity factor selected and cable type.

Four output impedances are available (25, 50, 75, and 100 ohms) and a velocity factor between 0.30 and 0.99 will meet any cable test requirements

Enhanced key pad navigation
Control of the TDR1000/2 has been simplified with each key having a dedicated function, such as cursor left and right, Velocity factor, range etc. Training times are dramatically reduced, and with less chance of time consuming mistakes, productivity is improved.

TX Null
TX Null eliminates the ‘dead zone’ at the start of the displayed trace, normally obscured by the transmission pulse. By adjusting the TX Null control the user can see these ‘near end’ faults clearly.

Fast Find key
Reduces the time taken to find major reflections on the cable. One press of the find key automatically adjusts the range and gain and positions the cursor to the major event on the cable within seconds, removing the need for the engineer to gradually scroll through the ranges looking for the fault or the end of cable reflection.

Description

The Megger® TDR2000/2 is a state of the art, monochrome or colour, dual channel Time Domain Reflectometer, capable of identifying and locating a wide range of faults on metallic cables.

The TDR2000/2 has a minimum resolution of 0.1m and a maximum range of 20 km at VF=0.9 and 16 Km at 0.65 VF. The TDR2000/2 can perform single or dual channel measurements on a wide range of metallic cables. Active channels can be compared with each other or with previously stored traces from memory. Differential channel measurements are possible and cross talk between channels can also be identified.

All results are displayed on a high resolution, QVGA colour display. Full contrast adjustment provides optimum display contrast in a variety of ambient light conditions.
