The Megger TDR2010 US (1007-078) is a state of the art, dual channel, high resolution, compact Time Domain Reflectometers with a color screen for locating faults on paired metallic 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 ohms) as well as an auto impedance matching feature. The velocity factor can be set between 0.2 and 0.99 to meet any cable test requirements.

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 selected 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 full control and instant indication of distance between two points.

A trace comparison feature also allows close examination between trace conditions. Extra high resolution together with a white-light backlight, user definable color schemes give the graphical display a vibrance, aiding the user in identifying key events on the trace.

Trace Storage

100 internal trace memories provide for the storage and recall of test results. The traces can be recalled to the display for analysis or compared with an active display to aid in fault location.

Alternatively the stored results can be downloaded to a computer, via the USB port, using the TraceXpert software and USB lead provided.

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.

Color Schemes

The TDR2010 has 6 additional set color schemes on top of the Default and Outdoor schemes included on other Megger TDRs. There are also 2 custom slots where the user can specify their own scheme by setting up to 7 screen elements to their own choice of color.

Trace Tagging

The TDR2010 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.
