Operation
1.
Press the Power button, 4, to turn 1205CXB on.
2.
Connect a cable to the BNC connector, 2.
3.
Press the CFG button, 5, repeatedly until VOP is highlighted in the
ConFiG submenu, 24.
4.
Use the arrow buttons, 11, to set the VOP% to match the VOP% of the
cable. This can usually be found in the cable's datasheet under VOP,
Velocity of Propagation or Dielectric.
5.
Press the CUR button, 6, to highlight Cursor 1, 15, and if necessary, use
the left and right arrow buttons to position Cursor 1 at the start of the
launch pulse, 17.
6.
Press the CUR button again to highlight Cursor 2, 16, and use the left and
right arrow buttons to position Cursor 2 at the start of the reflected pulse,
18, as shown in the Display diagram.
7.
Read the distance, 20, or time, 19, to the discontinuity.
8.
Additional functions, such as changing measurement units, setting
date / time, loading a cable from memory, and saving and recalling
waveforms, can be accessed via the MENU button, 8. For details, please
refer to the 1205CXB Operation Manual.
9.
Press the Power button, 4, to turn 1205CXB off.
Waveforms
The display of the 1205CXB shows a launch pulse at the left hand side of the
display and a reflected pulse if any cable imperfections are within range.
Move Cursor 2 so that it is positioned at the start of the reflected pulse,
as shown in the Display diagram. The distance to the imperfection is
then displayed at the bottom of the display. You can change the units of
measurement in the MENU.
Open circuit and high impedance series faults will result in a positive (upward)
reflected pulse. Short circuit and low impedance shunt faults will give a
negative (downward) reflection.
WaveView
Radiodetection's WaveView PC program is a software package that allows you
to view, manipulate, print and archive cable signature waveforms produced by
1205CXB cable fault locator. Visit www.radiodetection.com for a download
link and usage information.
