Admissible characters are ASCII characters, numbers, spaces, hyphens,
dashes and underscore.
Category 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

Element Description
Graph resolution Is used to select the graph resolution in angular degrees. The smallest value
(0.25°) results in the highest resolution and the highest value (50°) in the low-
est resolution.
Default setting: 1°
The resolution selected here applies to the entire tightening program. How-
ever, each tightening step can be set individually, if necessary, e.g. to display
less interesting graph sections with a lower resolution.
Measuring points Is used to select the measuring points for creating the graph.
Value range: 100 - 2000
Torque unit Selects the desired unit to be used by the NEXO-OS operating system to
display and calculate the torque for this tightening program.
The pre-set value is the value selected in menu Settings during configuration
of the nutrunner.
The resolution and number of measuring points must be properly adjusted for each tightening process.
