4.8 Test Failed Screen
4.8.1 Open and Short Fault
In the event of an
Open
fault, the following is displayed:
ID1
FAILED
TIA568
L=94ft
Vp=71%
4 5 1 2 3 6 7 8 S
Open at remote end
Pin 7
4 5 1 2 3 6 7 8 S
Notice the word
FAILED
under the cable ID1 and also the detailed mes-
sage at the bottom of the display.
The graphical portion of the display also shows that the fault is an open on
pin 7 at the remote end by showing a break in the line at this point.
NOTE:
In the event that an open or short circuit fault occurs at
either end of a cable or link under test, the unit will show the fault
as at the near end or the remote end. These faults are the most
common and are mainly due to termination problems.
If the fault occurs some way along the cable or link under test,
then a display similar to the one shown below will occur. Notice,
that on this occasion the actual measured distance to the fault
is given.
In the event of a
Short
fault, the following is displayed:
ID1
FAILED
TIA568
L=94ft
Vp=71%
4 5 1 2 3 6 7 8 S
Short at 36ft
Pin 1 2
4 5 1 2 3 6 7 8 S
In this situation, the graphical portion of the display also shows that the fault
is a short between pins 1 and 2 and the short is drawn at an approximation
to the distance along the cable or link under test, at which it occurs.
