5 Operation Configuring the USM Go for test tasks

Phantom echo detector
You can use the function PHANTOM PRF to turn on the
phantom echo detector of the USM Go. When the func-
tion is turned on, phantom echoes become visible due
to a regular movement sideways.
Especially when inspecting forgings, it is recommended
to leave the phantom echo detector turned on perma-
nently in order to detect phantom echoes.
As long as no phantom echoes occur, no distinction can
be made in the echo representation between the set-
tings
ON and OFF .
As soon as the phantom echoes appear in the setting
ON , they can be recognized at once by a regular move-
ment back and forth (approx. 3/s). If this is the case,
vary the pulse repetition frequency until the phantom
echoes disappear or have at least become sufficiently
small.
Note
It is recommended to always leave the phan-
tom echo detector turned on. In this way,
problems are recognized at once.
– Switch to the second operating level.
