(3) Laser height
− Laser measurement height (in laser centering method)
The figure below indicates the measurement position when the laser centering
method is selected. The distance between the nozzle tip to the measurement
position which is radiated with a laser beam is called “laser height”. The laser height
is specified in the component data.
Figure 1.1.2.5 Definition of Laser Height
− Default Laser height
Default laser heights are set for some component types and heights. Table 1.1.2.5
shows the relation between component heights and default laser heights.
