DESCRIPTION
The Megger® TDR2000/3, TDR2010 and TDR2050 are state of
the art, dual channel, high resolution, compact Time Domain
Reflectometers with a colour screen for locating faults on paired
metallic cables.
All TDRs in this series have a minimum resolution of 0.1 m / 0.3 ft
and a 20 km / 65 kft maximum range depending on the velocity
factor selected and the cable type.
Various output impedances are available (25, 50, 75, 100, 125, 140
ohms, model dependent) and 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 TDR2000 series have a large, high resolution, colour, 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 colour schemes give the graphical display a
vibrance, aiding the user in identifying key events on the trace.
600 V CAT IV input protection
TDR2050 is the first TDR in this class to include a built-in 600 V
input protection filter. The ability to connect to potentially live
circuits means a more flexible instrument suited for a wider range of
applications.
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.
Step TDR function
The Dead Zone effect of a standard pulse TDR can mask near end
faults and make them undetectable. The addition of a step function
on the TDR2050 eliminates this problem.
Step TDR technology means that the signal is injected at full
strength and stays there until a disturbance is detected. This makes
step TDR technology perfect for detecting near end faults that
standard pulse TDRs can miss.
Distance dependant gain
This feature, built into the TDR2050, eliminates the drop off of
signal attenuation on longer lines by gradually increasing the gain
along the returned signal, enabling a more even representation of
the relative attenuation at all points along the trace.
