Light level adjustment

TIP
Optimum light levels depend on the materials of the board, mask frame and mark. Use the following method to find
optimum light levels.
1. Turn off all light units.
2. Turn on, one at a time, "Outer Light", "Inner Light", "Coaxial Light, "IR Outer Light" and "IR Inner Light" at the
maximum level, to see how clearly the mark can be seen.
3. Combine the light units that were effective, and adjust their light levels.
As a general guide for adjusting board mark lighting, try these suggestions.
• Flat surface marks reflecting light : "Coaxial Light" is effective.
• Flat surface marks made of copper oxide : "IR Inner Light" is effective.
• Marks with uneven surface diffusing light : "IR Outer Light" is effective.

1.4 Cursor teaching
In cursor teaching, a teaching window of any desired size is displayed on the vision monitor, and the position
data at the center of the window is input as the teaching position. The cursor teaching allows obtaining a more
accurate value than with normal teaching. Note that this function cannot be used unless the marks and patterns
fit in the vision monitor.
