For general information on operation, please refer to the
USN 52 R Operating Manual.

Attention:

You cannot estimate any flaw sizes with the DGS op-
tion of the USN 52R/USN 52L. You can only compare
the reflecting power of a natural flaw with that of a theo-
retical flaw (= disk-shaped reflector) at the same depth.

3.1

Storing a new probe

There are 13 probes including the corresponding param-
eters stored in the instrument. You can program another
probe.
