Velocity - GE USM 36 Series Technical Reference And Operating Manual

Setting the display range (function group RANGE)

VELOCITY

N o t e
If µs are selected as units, the function
VELOCITY is deactivated for safety reasons
and it does not appear on the display screen.
You can use the function VELOCITY to set the sound
velocity in the test object.
You can choose between different materials and their
sound velocities. The additional information TR. and
TRANS refer to the sound velocities in transverse wave
excitation mode. In longitudinal wave excitation mode,
the material name remains without additional informa-
tion.
If you deviate from a specified material velocity when
using the navigation, the material name is automatically
replaced by the information CUSTOM. You can set the
sound velocity by coarse adjustment steps or by fine ad-
justment (see Section Coarse adjustment and fine ad-
justment, page 4-11).
The adjustment range is 250 ... 16000 m/s.

USM 36 calculates all range and distance in-
dications on the basis of the value adjusted
here.
