[Figure a]
Laser scan direction
The offset function can be applied for converting
the reference gage dimension to a nominal dimen-
sion (Figure a).
In Figure a set the offset direction to “0” (positive).
Example of [figure a]
Let D = 20.0005
± 0.0015
mm
• Basic setup
Set up according to the requirement.
• Function setup
1. Segment = 2
2. Number of scans for averaging = 512
3. GO/NG judgment
a. Lower limit
= 19.9985 mm
b. Upper limit
= 20.0015 mm
4. Offset
a. Set the nominal dimension of the gage to 20.0 mm.
b. Direction = 0 (positive)

If the offset value is set to 20.0 mm, the guidance
display for the OFFSET guidance indicator ( ) turns
on, and the measurement is also replaced to 20.0 mm.

“ ” is displayed and single-run measure-
ment starts.
After the first measurement interval the measurement
value is displayed, and the GO/NG judgement result is
outputted.
TIP 1. To re-activate the offset function using the existing offset value and direction,
press the
MASTER
/
OFFSET
key. With this single key operation, offset can be achieved.
2. It is possible to obtain a deviation from the reference gage by offsetting (zero-
setting) it to “0.0”.
