1.2.3 Calibrating the multi-vision camera scale

When calibrating the multi-vision camera scale, a glass QFP specially designed for

machine adjustment is used. Have the glass QFP ready before beginning calibration.

Check the "Adjust Mode" parameter and PCB data.

Calibration of the multi-vision camera scale uses a glass QFP, so the machine must be

set to "Adjust Mode2" and the "MCH_SETUP" PCB data loaded into the machine.

You can check the currently selected PCB data and "Adjust Mode" on the status bar.
