59. Buttonhole control
The buttonhole gauge consists of a measuring rail and a dual-track forked light barrier.
The 90° out-of-phase signals generated when the measuring rail is moved are counted by the hardware, with
the total running up or down depending on the direction of movement.
The operator is requested to insert the measuring rail to the limit.
The measuring rail must be pulled out by pressing the „START“ button.
The counter reading is displayed in the form of a number.
If a value of min. 110 is not reached, an error message will be issued.
An evaluation window (OK or Error) is displayed after completion of the test.
Press the button „i“ = End (end of test with possibility to go to the next test)
The current test can be interrupted with the „i“ button.
If the „Full test“ mode is activated, the next test will be automatically executed after completion of the test.
