T-506 User Manual Version 3.2 | 28
Move the detector along a small distance along the cable path and observe changes in the
operating interface:
Operator interface
i)
In the User mode, if after multiple readings in the same position, the test results
show that a water ripple effect (below), it indicates that no fault point has been
found, and it is necessary to continue moving the detector.
ii)
If, after multiple readings in the same position, the test result display changes to a
solid ring, it indicates a suspected fault sound has been identified.
iii)
Continue to take measurements at the same position, the ring starts to flash, and
the acoustic magnetic delay value at the current position is given in the upper right
corner. The position of the detector is determined to have identified a fault
discharge sound, and the fault point has been found.
[
Note
] During the test, the APP also records the acoustic and magnetic delay value of
the instrument at the last trigger, which is shown in the upper left and it records the
minimum delay value identified at the bottom. This information helps to show
whether you are approaching the fault point.
