Velocity Measurement - GE LOGIQ A100 Technical Publication

Velocity Measurement

+ Velocity of a moving structure is the rate of change of its
displacement. It is determined by placing an arbitrary
line tangent to the steepest slope of the structure in a
M–Mode trace and measuring its slope which is equal to
+
the velocity of the structure. It is expressed in meters per
second.
A "
As in all M–Mode measurement freeze before performing
any measurement.
Press MEASUREMENT to display the General
Meas
Measurement Menu. Simultaneously an open ended " "
appears on the screen.
Select [3].
If the appropriate measurement was already performed
3
the Velocity is calculated and displayed.
Use the TRACKBALL to move the open ended " " cursor
to a point tangential to the steepest slope of the M–Mode
trace.
TB
Press SET set to fix one end of the line. A second cursor
and a dotted line appears.
Use the TRACKBALL to move the second open ended
" " cursor to a point such that the dotted line is tangential
to the steepest slope of the M–Mode trace of the
TB
structure of interest.
Press SET . The velocity of the structure is displayed at
the right side off the screen.
Up to four measurements values can be displayed on
the screen.
