4.2 Calibration of Presetter
4.2.1 Set the camera’s working distance
The working distance is defined as the distance between the front edge of the cam-
era tube shield and the object to be measured, for example a tool cutting edge.
This measurement is preset by the design and the production tolerances of the cam-
era tube shield (lens).
The working distance must be set following the instructions in the
enclosed calibration log with a permissible tolerance of 100 ±
0.1mm. (3.937 ± .004”)

Urma AG, Switzerland www.urma.ch page 13
4.2.2 Check illumination
After the working distance is checked, the homogeneity and brightness of the illumi-
nation must be set. For this, you must not have anything in the camera’s visual field.
To check the illumination the greyscales are checked in the camera’s horizontal and
vertical alignment on both edges of the image as well as the middle of the image and
the results shown on 6 lines.
The illumination reaches its optimum setting if these lines are as horizontal as possi-
ble and within the horizontal tolerance range marked by 2 purple lines.
You access the operating mode for setting the illumination using the following menu
steps:
Main menu Sub-menu 1 Sub-menu 2
Setup ÖImaging ÖIllumination
The TCAM2 displays the following image with 6 grey scales (illumination lines):
Procedure:
1. Select the illumination check with the "Illumination" operating mode. The
horizontal tolerance field appears with the illumination lines. "Illumination"
appears in the status window.
2. If not all 6 greyscale lines on the LCD are inside the tolerance field, you
have to adjust the light source. Remove the cover of the light source as
shown on the picture below.
Tolerance field

Urma AG, Switzerland www.urma.ch page 14
3. If the greyscale lines are not horizontal you have to adjust the position of the
light to the optical axis. For this you unscrew the 3 slotted-head screws until
you can move the whole print. On the screen you will see what the move-
ment of the print will cause with the greyscale lines. You move the print until
all greyscale lines are horizontal.
Potentiometer slotted head screws
4. If the greyscale lines are horizontal but not within the tolerance field, you can
increase or reduce the intensity of the light on turning the little screw on the
potentiometer.
5. Put back the cover and exit the illumination check with ESC or by selecting
another operating mode.

4.2.3 Align camera
When aligning the camera you must ensure that a known straight contour running parallel
to the vertical axis of your system also runs parallel to the vertical axis of the cross hairs in
the TCAM2.
You access this operating mode using the following menu steps:
Main menu Sub-menu 1 Sub-menu 2
Setup ÖImaging ÖAlign camera
The TCAM2 then displays a histogram that shows the deviation away from the vertical
axis.
The displayed value for the angle should be
less than 0.02 °
Procedure:
1. Set the master mandrill on the screen it is not necessary to set in the cen-
tre.
2. Select the "Align camera" operating mode. The TCAM2 then goes into the
"Align camera" operating mode and you will see a histogram along the verti-
cal axis of the cross hairs. "Align camera" appears in the status window.
3. Turn the camera on its support around the optical axis until the histogram
has the smallest possible deviation.

5.1.2 Live picture
The object to be measured and the various adjustment aids depending on the operat-
ing mode (cross hairs, adjustment bars, test LED, measuring lines, analysis window,
measuring results) are displayed on the live picture operating mode.
5.1.2.1 Cross hairs
The cross hairs give an overview of the position of the contour.
In the "Fixed axis" operating mode the measurements always refer to these cross
hairs with the origin at 0.0 mm or inches. In the "Preset" and "Maximum" operating
modes these cross hairs remain so that the tool reference for the whole measuring
structure is retained. Additional red measuring lines are created on the object’s pro-
file depending on the measuring method determined or selected.
5.1.2.2 Adjustment bars
Adjustment bars are provided for both directions in the "Fixed axis" operating mode.
The pointer in the X adjustment bar gives the contour’s positive or negative deviation
from the measuring line in the X direction, the Z adjustment bar does the same in the
Z direction. The different colours on the bar show the distance of the contour from the
measuring line.
The different setting ranges have the following limits:
Colour Setting range
Grey ± (16 – 60) µm
Yellow ± (4 -15) µm
Green ± (0 -3) µm
5.1.2.3 Test LED
The test LED indicates whether the TCAM2 can correctly apply one of the imple-
mented measurement functions to the object displayed.
