Instruction

Manual

The ROI now has to be suitably resized and positioned: follow the instructions provided earlier
during this procedure.

We access the Adjust mode by pressing the

STATUS

button. Let's increase the minimum edge

limit value to 3 using the

ARROW UP

button.

Use the

RIGHT ARROW

button to set the type of variation to be detected. Use the

ARROW UP

button to see the Black to White value.

Now press the

STATUS

button to enter Monitor Mode and check that the tool functions properly.

The sensor now behaves correctly. As the result is satisfying, press

STATUS

again and move on

to defining the behaviour of the outputs.
