Step 1
1.
Go to Inspection Page.
2.
Click Adjust Conveyor.
3.
Set the following:
– Thickness, 4mm.
– Width, 154mm
4.
Click Set..
The conveyor starts to adjust to
154mm width.
Step 2
1. Place the 2D and 3D target onto
the inlet section in the orientation
shown below. The 2D target
should be loaded head in first.
Ensure the 2D lighting cable is in
the cavity.
2.
At Conveyor, click PCB In. The
target loads into the inspection
section, stops at the stopper and
clamps.
3.
At Miscellaneous, click Open
Door. Open the machine cover.

saturated.
b. As you can see from image
below, the corners should be
connected and the “White
regions” are not totally white
but have lower gray level
value.

Click Continue to start 2D
calibration, calibration takes about
30s to complete.
