object. You can use sound velocities between 1000 and
15000 m/s.

Attention:
Always ensure that the function MTLVEL is correctly
set. The USM 35X calculates all range and distance
indications on the basis of the value adjusted here.
– Select the function MTLVEL.
– If required, toggle between coarse and fine adjust-
ment.
– Adjust the required value by means of the right-hand
rotary knob.

D-DELAY (Display starting point)

Here you can choose whether to display the adjusted
range (for example 250 mm) starting from the surface
of the test object, or in a section of the test object
starting at a later point. This allows you to shift the
complete screen display and consequently also the
display zero.
