7.3
Create a new measuring program
A measuring program can be directly created on the
control and evaluation unit independently of the
measuring instruments. Therefore, programs can be
created at any location. Before starting to create a new
program, determine the order in which the
measurements are to be executed. At the points where
you might insert one or more program steps later on,
you should add one or more „empty“ measuring steps.
Explained in the following menu are how to implement
settings, how to make changes to the record head, to
the program head and to the program steps, for
example tolerances, nominal values, etc.
7.3.2
Changing a program head
1 - Step-by-step mode
When entering NO the workpiece will be measured
without the height measuring instrument asking any
further questions.
With YES, the question will appear in the display after
every single program step:
2 - Positioning the probe
YES
Before starting the measurement, the height
measuring instrument automatically positions the
probe to the height of the characteristic. The duration
of the pause following a positioning operation is
given in seconds.
NO
Contacting takes place automatically without stopping
at an intermediate position.
3 - Plausibility factor
The plausibility limits result from the multiplication of
the allowances with the factor to be entered. If a factor
of 1.0 is entered, any value outside the tolerance limits
is judged as „implausible“ and must be accepted or
rejected by the operator, even if the „step-by-step“
mode is not in use. Implausible measuring values are
not saved automatically!
4 - Parts per sample
Here you can define how many workpieces a sample
contains (any number between 0 and 250). Enter the
required sample size and press the ON/OFF key to
accept the proposed sample size.
After a sample has been checked completely, the
height measuring instrument completes the program
run.
If the sample size is smaller than 2, then nothing can
be calculated (statistics). In the top left of the display
will appear the number of runs and the actual
characteristic number.
