After the point-line perpendicular projection point calculation, the INC coordinate of the ES-9Q will be
preset to the projection point of line
& point , operator move to 0.000 in INC coordinate, then this
is the projection point
A B
C.
3. After operator viewed the projection point feature's parameters, operator can store this point feature
into the memory of ES-9Q as per following procedure.
press key to store the feature into the memory
ES-9Q asking the feature memory
location to be stored.
There are 100 feature memory available in ES-9Q, they are feature 0-99 respectively, in this example, we
are going to store this point parameters as feature 10, procedure are as follows
enter the feature memory
location. then the point parameters
are store into memory location
as feature 10.
