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. |

- 3 Configurations 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.
