Mask Editor Menu
Limit Mask Softkey
The limit mask softkey selects the active limit mask for the mask editor
menu functions. Limit masks are stored in pairs, where m1 or m3 contains
the upper limit mask and m2 or m4 contains the lower limit mask.
Horiz-Vert Softkey
The horiz-vert softkey changes the horizontal and vertical field values,
and the position of the x2/y2 markers on the screen during mask edits. The
acceptable vertical settings are from 0 (y2 at the bottom of the screen) to 255
(y2 the at top of the screen). The acceptable horizontal settings are from 0
(x2 at the left of the screen) to 500 (x2 at the right of the screen).
When horizontal is selected, the vertical y2 marker is slaved to the horizontal
x2 marker. As the x2 marker is changed, the y2 marker follows the displayed
active limit mask and updates the data values at each location. If the mask
has a hole present, the y2 marker are not changed.
You can move the xI/yl1 only when the mark point softkey is pressed.
Clear Mask Softkey
The clear mask softkey replaces the entire active limit mask with holes
(blanks the screen).
Main Mask Menu Softkey
The main mask softkey returns you to the main mask menu.
