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.
1
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.
