Go to VPS by pushing [EDIT] and use the arrow keys to navigate to VPS  >PROBING>CALIBRATION>Step 1 (Tram and Indicate Work Probe) .
To select the tool position that your probe was installed in press [Tnn] and [ATC FWD] or [ATC REV]. This will call the probe into position.
Push [SETTING] and use the arrow key to navigate to User Positions>Spindle Center Line. Write down the X-position  stored in the appropriate setting for the type of turret on your machine. VDI/Hybrid turret: Setting 319 or BOT/BMT turret: Setting 320
Hand Jog the X-axis to the written down X-position. Make sure that the Y-axis position is zero. Then Hand Jog the Z-axis so the co-axial indicator will sweep the probe stylus tip.
