Name, Machine Name and Operator Name.
Serial Communication: Enables the user to set the Serial
communications parameters.
Cross hair and mounted edge detector probe may have physical
position offsets, hence to obtain accurate results; we must do the
cross calibration process for every magnifications.
If we don’t execute cross cal, and if we probe a circle by cross
hair and by edge detector, in both cases, we will get diameter
equal but centre coordinates will be different.
In this mode the user has to probe a circle using Edge detector
and again probe the same circle using cross hair. The result of
Cross calibration is displayed as shown below.
Save the changes and exit Edge detector calibration.

Measurements using Edge Detector mode:
For performing feature measurements using Edge detector,
select Edge mode by pressing { } soft key in DRO mode.
Now press any feature key and probe points using Edge detector.
Rest procedure remains same as explained in Geometric Feature
Measurement chapter.

Tolerance
Tolerance helps users maximize productivity. A tolerance is an
acceptable deviation from the nominal specification of a part. For
example, a pin might have a nominal diameter of 5.000 mm. Without
tolerance, only pins with a diameter of .5.000 mm are acceptable.
This means that pins that measure 4.999 mm or 5.001 must be
rejected. With tolerance an acceptable deviation from the nominal
specification is defined. For example, the diameter of 5.000 mm
might have a tolerance of +/- .05. This means that pins as small as
4.950 mm and as large as 5.050 mm are acceptable.
