Absolute zero point
The absolute zero point is the reference point for all stored
tool references.
For this reason, before saving tool references, it is neces-
sary to store the absolute zero point as follows.
1. When you click on the menu point “absolute zero point”
it will appear the window on the left. Enter the known
dimensions of the master mandrill.
2. Press on the Record bottom on this window and it will
open a new Window showing “1.point”
3. Move the horizontal line of master mandrel to the cen-
ter of the reticule ( You are in the “measure centre”
mode ) to measure the length. Click “OK”.
4. Move the vertical line of the master mandrel to the cen-
ter of the reticule to measure the diameter. Click “OK”.
After this, the system stays in the measure centre
mode and you can check the measurements of the
master mandrel.
You should measure the engraved values of the mas-
ter mandrel
