14.3.7.3. Camera Offset Calibration

Measure the offset between the center of the fiducial camera and the first head (Head 1) of

each gantry.

This offset measurement must be completed to be able to use the Auto Nozzle Change

function for calibrations that follow. This process is performed only in the Manual Mode.

A calibration glass must be used to perform this calibration and calibration is required only

for a single fix camera even if there are two fix cameras.

 Calibration using a calibration glass (fix camera option)

1. If the <8. Camera Offset> button is clicked, the message “Put a Tool Plate on

Upward(Fix) Camera 1. And Adjust Tool Center. If you Finish it, Click [Next].”

appears in the message box. Click the <Next> button to move down the Z axis of the
