8.2 Measuring methods
8.2.1 Fixed axis
Here all measurements relate to the original cross hair co-ordinates.
You access this operating mode using the following menu steps:

Fixed axis
After selection the system analyses the object contour and automatically suggests a
measuring procedure for carrying out measurements immediately. The measuring
procedure used is displayed in the status window at the same time. If an alternative
measuring procedure is required it is possible to enter the measuring procedure ma-
nually by pressing the button in the status window.
Procedure:
6. Move the object into the camera’s visual range.
7. Roughly set the picture focus by turning the object on its support to its
maximum deviation.
8. As soon as the object to be measured is within the focussing area, the ad-
justment bars are displayed. The TCAM2 automatically determines the best
measuring procedure and the test LED goes green.
9. Move the edge of the object as close as possible to the cross hairs so that
the arrow of the adjustment bar corresponding to the deviation direction is in
the green area.
10. The focus is finely adjusted by once again turning the object in the direction
of the focus level until the arrow shows the maximum deviation in the corre-
sponding adjustment bar.
11. If the TCAM2 does not set the measuring procedure or the analysis window
to your requirements, change this manually.
The analysis window should always be around the co-ordinate origin point.
12. Align the contour on the measuring lines. Note the adjustment bars that give
you optimum support for this.
13. If the adjustment bar pointers are in the middle you have found the best
possible position for the object. You can now further process the data and
start measuring again.
