MEGGER TDR2010 Time Domain Reflectometer

MEGGER TDR2010 Time Domain Reflectometer Cable Fault Locator for Twisted Pair Metallic Cables

The MEGGER TDR2010 Time Domain Reflectometer Cable Fault Locator is a state of the art dual channel, dual trace Time Domain Reflectometer (TDR) designed for locating faults on twisted pair or coaxial metallic cables. It can also be used to locate discontinuities in a connector, printed circuit board, or any other electrical path. The equivalent device for optical fiber is an optical time-domain reflectometer. It is the first TDR in its class to have 150V CAT IV input protection filter built in, giving the ability to connect to known live lines. This is particularly useful for detecting illegal taps without having to power down the line.

MEGGER TDR2010 Time Domain Reflectometer Highlights

• CAT IV 150V input protection filter built in
• Step and pulse TDR selections
• Distance dependent gain
• Trace tagging
• 2ns pulse width
• Designed for use on all metallic paired cables

The TDR2010 has a minimum resolution of 0.1 m / 0.3 ft and a 20 km / 65,000 ft maximum range depending on the velocity factor selected and the cable type. Various output impedances are available (25, 50, 75, 100, 125, 140 ohms) and an auto impedance matching feature. The velocity factor can be set between 0.2 and 0.99 to meet any cable test requirements.

MEGGER TDR2010 Time Domain Reflectometer Features and Benefits:

The TDR2010 has a large, high resolution, color, WVGA display with easy set up features. Directional control buttons, together with soft keys, provide intuitive and easy operation for the user.

An AUTO selection option ensures that the most effective parameters are chosen depending on the range required, aiding rapid diagnosis of the TDR trace. The ability to manually override the auto function allows fine tuning to enable identification of hard to determine faults. Dual trace and dual cursor capabilities allow full flexibility, giving the operator complete control and instant indication of distance between two points.

Fault Identification

Megger’s own built-in AutoFind mode allows for speedy identification of faults. One press of the AutoFind key automatically adjusts the range and gain, and positions the cursor to the first major event on the cable. Press the AutoFind key again and the cursor will jump to the next detected disturbance.

MEGGER TDR2010 Time Domain Reflectometer Finds End of Cable

TDR2010 also incorporates a “Find End” function which allows the user to automatically search the trace to identify the end of the cable under test. This is useful in situations where a fast cable length measurement is required. For those who wish to maintain manual control, manual operation allows full override access to refine the response for easy fault identification.

150V CAT IV Input Protection for Live “HOT” Circuits

TDR2010 is the first TDR in its class to include a built-in 150V CATIV input protection filter. The ability to connect to potentially live circuits means a more flexible instrument suited for a wider range of applications.

Trace Tagging/Naming for Saved Traces

MEGGER TDR2010 Time Domain Reflectometer also incorporates a trace tagging feature which allows the user to add a name to saved traces. This could be the circuit ID, building name or any other identifying text the user wishes to save with the trace. A text string of up to 32 alphanumeric characters can be stored against each trace and this can consist of upper case letters including accents.
