Explanation:
Step
The program step number should be a number
between 1 and 100, in order to display the contents of
a certain program step. The program step number is
automatically increased by 1 after having confirmed a
program step.
Group number (left column)
Number of a program step group, which enable it to
cover an entire workpiece family with a single
measuring program. If certain measurements are not to
be carried out on every workpiece, the measurements
(program steps) in question can be assigned a special
group number. These group numbers cause the
measurements (program steps) to be carried out only if
this is explicitly confirmed at the program start.
Group (right column)
Each group can be assigned a name. The name,
however, is not necessary for the functioning of the
program. The list of all program subgroups is however
displayed when starting a measuring program.
Measuring functions
The displayed measuring function is accepted when
leaving this field. Program steps without a
measurement or computation function are considered
nonexistent.
Please remember that the functions „Bore“, „Shaft“,
„Polar coordinate“ and „Groove“ require two program
steps each, while the „Index circle“ requires three.
Characteristic (Charact.)
7.3.3 Changing a program step
For every program step, the parameters must be
entered. The parameter menu looks as follows:
With the aid of the following keys you can move
around the input field
+ / - scroll between program step to program step
Cursor key, move left or right within the input
field
Tab function - to move to another input field
Skip to the start position (step__ 1)
Switch between upper and lower case
The characteristic is assigned a name that may
comprise up to 11 alphanumerical characters
Nominal value (Nom. val)
The nominal value is entered with the measurement
unit (mm or inch)
Upper allowance (Upp. all.)
Upper allowance relative to the nominal value, for
example: 0.015
Lower allowance (Low. all.)
Lower allowance relative to the nominal value, for
example: -0.015
Pareto upper / lower tolerance (Paret. UT / LT)
To do this, the weighting factor for sizes above the
upper tolerance limit must be entered.
Also see statistics, point 8.6 Pareto menu
Measured characteristics can also be evaluated
attributively in a Pareto chart. Here, all sizes outside
the allowance limits are considered „Rejects“, while all
other sizes are considered „Accepts“.
Comment
A comment can be entered here, which may be
important for the following program step
(measurement). The comment is displayed along with
the result of the current measurement program step.
