Tutorial 7: Default and Custom Mask or Limit Line Testing
Tutorial 7: Default and Custom Mask or
Limit Line Testing
The 70820A menus allow you to create and display up to eight limit lines and
masks at one time. Five default mask/limit-line shapes are provided for your
use:
• hexagon
• square
• equilateral triangle
• inverted equilateral triangle
• flat line
You can stretch, shrink, or move any mask. It is also easy to add additional
points or delete unneeded points from any shape. Both limit lines and masks
can establish either upper or lower limits for a response.
Custom masks are easy to create by editing the supplied default shapes. The
compatible modes are eye, eyeline, and pattern.
