The Adjustment tab is activated for the tool type Special tools. For Measuring tools the tab is instead called Calibration. Except for the difference in name and certain headings, the tabs are identical.
All the fields with headings in italic font (including the adjustment / calibration points), inherit all this data from the properties of the selected tool group.
Under the Adjustment / Calibration Settings you can enter settings for the adjustment or calibration of the tool.
Under the section Cycles you will see the tool's number of cycles both in total and since the last calibration.
Under the Adjustment / Calibration Info you can see different adjustment and calibration info.
Under the Adjustment / Calibration Points you can add, modify or delete adjustment/calibration points.
