System functions
System functions support a wide variety of mea-
surement and setup activities. System functions
include:
• Datum lock indication
• Undo
• Magnification (Mx)
• Unit of measure (mm/Inch)
• Setup
Datum lock indication
The lock icon indicates that features are locked to the datums used when they were measured. When the
lock icon is not shown, new datums are applied to all features in the feature list as they are created.
Undo
The Undo function is very similar to the Windows undo function and erases the last measurement or
feature list activity step. The Undo function only erases the last step, sequences of steps cannot be
erased using undo.
MX
The MX (shown here as M1) function provides access to a drop down list of available video magnifica-
tions. Touching the MX button shows the list of available magnifications. Touch the desired magnifica-
tion to select it.
