Krautkramer USN 52R/USN 52L Option DGS

Note:

If the reference echo symbol does not appear, no refer-
ence echo was recorded. Possible reasons are:

• The reference echo is outside of the monitor gate.

• The amplitude of the refernce echo is either too low

or too high.

• The reference cho comes from a side drilled hole,

and the conditions to use it are not met (ref. to
chapter 3.2).

Correct the settings correspondingly and record the
reference echo again.

– Enter the required recording level in the

ERS

function:

– Switch the DGS mode on in the

DGS

function:

Note:

The reference echo must have the highest amplitude
within the gate, as shown in the figure below:
