Term/abbreviation Meaning
AUTO mode Operating mode of the Checkbox for automatic parts testing (pre−set when
CHB−C... is started).
Bad part A test part on which at least one feature lies outside the tolerance.
CHB−C−... A device of the type Checkbox Compact (without transporting device) for
identifying conveyed parts of a parts type.
C−value During the Teach procedure the C−value shows the extent of the scatter of
characteristics of the sample parts. The C−value specifies the maximum
value of the scatter of characteristics for the current feature which differs to
the greatest extent.
Deviation The Checkbox assesses the feature of a test part which differs most from
the Teach data. The smaller the value of the test part deviation, the more
accurately the test part corresponds to the sample parts.
Feature Characteristic features are ascertained from the contour data of the sample
and test parts. These are e.g. length, height, etc. as well as a feature for
each configuration tool (CheckOpti).
Good part A test part on which all features lie within the tolerance.
Laser class Identifying the laser irradiation as per EN 60825−1:1994 + A1:2002 +
A2:2001. Laser devices are classified according to the increasing degree of
danger into classes 1, 2, 3A, 3B and 4.
Class 2
An accidental, brief effect (up to 0.25 s) will not damage the eye.
With longer lasting effects damage to the eye is possible.
Laser devices of class 2 may be used without further protective measures,
providing it can be guaranteed that during operation the user is not required
to look intentionally over a long period (longer than 0.25 s), or to look
repeatedly into the laser beam or mirror−reflected laser beam.
Class 3B
Lasers of class 3B can cause serious eye injuries. Long−period irradiation by
a laser of class 3B on the skin causes erythrocytes (red skin patches),pig
mentation, burns or photochemical damage.
Orientation The parts to be tested by the Checkbox can be placed on the conveyor belt
facing in different directions. During the Teach procedure you can define the
orientations by showing the different directions. Orientation 1 is the pre
ferred orientation (nominal orientation).
