CFL535G
Advanced Dual Channel TDR
DESCRIPTION
The Megger
resolution, compact Time Domain Reflectometer with a color
screen for locating faults on paired metallic cables.
The CFL535G has a minimum resolution of 0.3 ft /0.1 m and a
60 kft/20 km maximum range depending on the velocity factor
selected and the cable type.
Five output impedances are available (25, 50, 75, 100, 125
ohms) 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 CFL535G 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 tones and color give the
graphical display a vibrance, aiding the user in identifying key
events on the trace.

CFL535G is a state of the art, dual channel, high
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 Xpert mode allows for speedy
identification of faults. One press of the Xpert key
automatically adjusts the range and gain, and positions the
cursor to the first major event on the cable. Press the Xpert
key again and the CFL535G will jump to the next detected
disturbance.
For those who wish to maintain manual control, manual
operation allows full override access to refine the response for
easy fault identification.
TraceXpert PC software
The CFL535G comes complete with the Megger TraceXpert
software which gives full control over downloading, reporting
and uploading of saved trace results. Designed around a
database and programmed for ease of use and simplicity,
TraceXpert offers the ideal application for all your data
processing requirements.
