Pitch circle diameter (PCD)
This function allows the calculation of a pitch circle diameter
(PCD) :
1. Press the corresponding symbol to open the menu
2. Enter the number of the 1
st bore (a) and press the Enter
key. Repeat the sequence for all following bores
(minimum 3 bores/shafts). All center points entered,
press the Enter key once more.
3. Attribute a number (one which does not yet exist) to the
center point of the pitch circle diameter, enter it in the
corresponding field (b) and press Enter.
The calculated values will be stored in the buffer as follows:
Number of the center point (c)
PCD 99
Mean diameter value (d) DIA 9999.9999
Min. diameter value (e) DMIN 9999.9999
Max. diameter value (f) DMAX 9999.9999
X coordinate of the center (g) X 9999.9999
Y coordinate of the center (h) Y 9999.9999

Polar coordinate system
To select the polar coordinate system, press the
corresponding symbol on the touch screen. To return to the
cartesian mode, press again the corresponding symbol.

Back to the original coordinate system
To return to the original coordinate system (status after
acquisition of all center points) press the symbol shown at the
right and confirm.
This sequence will be stored in the buffer as follows :

Creation of a reference center point
It is possible to create a hypothetical reference point.
1. Select the symbol shown at the right side
2. Enter the number of the center point (a)
3. Enter the X coordinate of the center point (b)
4. Enter the Y coordinate of the center point (c)
5. Confirm by pressing Enter.
The point will be stored in the buffer as follows:
Number of center point
PT 99
X coordinate of the center point X 9999.9999
Y coordinate of the center point Y 9999.9999
