Three Configuration Options

The TDR2000/2 comes in three configurations: TDR2000/2 Monochrome primary cell A fully featured high resolution TDR with backlit monochrome display and powered by 8 x AA (LR6) batteries.

TDR2000/2RM Monochrome rechargeable

As the TDR2000/2 but with a rechargeable NiMH battery pack and charger in place of the Dry cells.

TDR2000/2R Colour rechargeable

As the TDR2000/2RM but with a colour high resolution display providing excellent trace separation in dual tracemodes. The unit is also powered by a rechargeable NiMH and includes battery charger.

Intermittent Mode

An ‘intermittent mode’ continually updates and shows any transient reflections. Any intermittent fault leaves a permanent record on the display, capturing elusive faults.

Dual cursors

The TDR2000/2 can display either single or dual cursors. Single cursor mode displays the distance from the start of the cable to the cursor. In dual cursor mode the distance between faults can be measured.

Fast Find key

One press of the find key automatically adjusts the range and gain and positions the cursor to the major event on the cable.

Tx Null

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

Output pulse control

Both the amplitude and width of the output pulse can be adjusted to provide the best possible reflection for accurate location of cable faults.Interactive Help Screen A full graphical help screen is available with keyboard layout and individual key operation at the press of a button.

Trace Storage

15 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, over the RS232 port, using the TraceMaster software and RS232 lead provided.

Trace Master PC Software

Trace Master provides download and upload facilities between the TDR and a computer. Traces can be individually selected, saved to a PC and annotated by the user. Historical information can be reviewed on the PC or recalled to the TDR for comparison with current measurements. Tracemaster is the ideal tool for cable documentation. Results can be printed from the computer for inclusion in documents.

Power source

The TDR2000/2 can be supplied as a standard battery powered unit or in a rechargeable version, as the TDR2000/2RM or TDR2000/R. Fitted with a NiMH rechargeable battery pack the TDR2000/2R and TDR2000/RM are supplied with the charger as standard.


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.
