MEGGER TDR Time Domain Reflectometers Cable Fault Locators

MEGGER TDR Time Domain Reflectometers Cable Fault Locators leading models are state of the art dual channel, dual trace Time Domain Reflectometers (TDRs) designed for locating faults on twisted pair or coaxial metallic cables. They are 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 600V CATIV 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.

Product Highlights

• CAT IV 600 V 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
• 20Km (65,000 ft.) range with 1 meter resolution

MEGGER TDR Time Domain Reflectometers Cable Fault Locators Leading Models Features:

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 TDR Time Domain Reflectometers incorporates a “FindEnd” 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.

600 V CAT IV input protection

MEGGER’s leading model, TDR2050, is the first TDR in its class to include a built-in 600V CAT IV input protection filter. The ability to connect to potentially live circuits means a more flexible instrument suited for a wider range of applications.

MEGGER TDR Time Domain Reflectometers Cable Fault Locators feature Trace Tagging

MEGGER’s leading TDR models 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.
