NOTE
Chapter 9 Flatness Measurements
Completing the Set Up Flatness Screen
Measuring the first line on the grid
To make the measurement, follow these steps:
Move the reflector to the first station.
On the Collect Data: FLATNESS screen, select Reset Position.
This tells the system that the current position of the reflector is the "zero"
point from which the surface plate flatness will be measured (that is, the
first data point for this line).
If necessary, use the online help to complete the rest of the fields on this
screen.
Select Record.
If you are using the optional remote control unit, press the Record button.
Move the reflector to the second data point on the line to be measured.
Select Record.
Continue, moving the reflector to each station along the line and recording
measurements until you have recorded data at the last station on the line.
After the last measurement on each line is recorded, the Analyze Data:
FLATNESS screen is displayed (Figure 9-14).
If at any point the Reset Laser message flashes, the laser beam path has
been broken. Move the reflector back to the first point measured, then
select Reset Position to reset the system. Now you can return to the last
station you measured (check your repeatability) and continue taking
measurements.
