TDR2000/2P
DESCRIPTION
The Megger® TDR2000/2P is a state of the art, Monochrome
dual channel Time Domain Reflectometer, capable of
identifying and locating a wide range of faults on metallic
cables from a few meters to 20 km depending on cable type.
The TDR2000/2P is ideal for engineers with little TDR
experience. The TDR20000/2P can perform single or dual
channel measurements on a wide range of metallic cables.
Cables can be compared with each other or with previously
stored traces from memory. Good and bad cores in multi
core cables can be compared and just the difference
displayed.
Either dead or Live cables to CATIII 300 V Phase to earth
or 415 V phase to phase can be tested. The TDR2000/2P
is supplied complete with pairs of 2 metre long fused test
leads, fitted with 30 mm gape crocodile clips for easy
connection to large diameter cables.
No blocking filter is required.
TDR2000/2P FEATURES
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 TDR2000/2P 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 TDR2000/2P is supplied with a NiMH rechargeable
battery pack and charger as standard.
