Standard tightening step
The standard tightening step fulfills the usual requirements for a tightening step through a selection of
target, additional, and monitoring functions.
This panel defines the general start properties of the tightening step.

Target
This panel provides the additional parameters required for the tightening step, which have an effect on
the tightening process (e.g. start-up suppression) but cannot interrupt it.
Click the icon to insert a new tightening step in the tightening program before the tightening
step selected. Double clicking the tightening step or the respective icon opens the corre-
sponding dialog for entering the parameters.
Tightening step dialog - designation panel
Description
Is used to enter the name of the tightening step. Appropriate designations for
the tightening steps make it easier to understand the tightening programs in
the program overview (e.g. 2, A first tightening, 3, A end tightening).
Is used to select the category for determining the quality code. The quality
code describes whether a tightening job was evaluated as OK or NOK. In
case of an NOK evaluation, the cause will also be described. In NOK cases,
the category is used as a detailed distinction, so that a different quality code
can be output in different tightening steps for the same NOK cause (e.g. M
< M–).
Possible categories include e. g.:
– Tightening
– Pre-tightening
– Final tightening
– Loosen
– Rework
Is used to select the graph resolution in angular degrees.
The settings in the start step specify the graph resolution for the entire tight-
ening program. However, this can also be set individually for each tightening
step. This allows you to display steps with very low resolution and steps with
very high resolution within one tightening job. The entire course of the graph
can be made visible without increasing the number of graph points.
– Resolution
Setting for the resolution of the graph in angular degrees. The smallest
value corresponds to the highest resolution and the largest value to the
lowest resolution.
Default setting: Same as on start-up
The following resolution steps are possible:
– 0.25°
– 0.5°
– 1°
– 2°
– 5°
– 10°
– 20°
– 50°
The actual graph resolution depends on the nutrunner configuration.
It is usually not possible to display the entire course of the graph if you use
the maximum resolution (0.25°) and the maximum number of measuring
points (2000). In such cases, you should adjust the resolution, i.e. make it
less high.
