2.7.7 Z-Compensation

Z-Compensation calculation can enabled/disabled if Z-Compensation calibration is done. Following parameters can be
used to fine-tune the compensation:

X Bright To Dark Mul:

Z-Compensation multiplication factor for X-edges from bright to dark. Direction is from left to right. 0 = no
compensation, 1.0 default.

X Dark To Bright Mul:

Z-Compensation multiplication factor for X-edges from dark to bright. Direction is from left to right. Direction is
from left to right. 0 = no compensation, 1.0 default.

Y Bright To Dark Mul:

Z-Compensation multiplication factor for Y-edges from bright to dark. Direction is from top to bottom. 0 = no
compensation, 1.0 default.

Y Dark To Bright Mul:

Z-Compensation multiplication factor for Y-edges from dark to bright. Direction is from top to bottom. 0 = no
compensation, 1.0 default.

Threshold:

User has an option remove points where calculated Z-Compensation is big. This is useful feature if the material has a
strong texture and compensation is suboptimal for those points.
Method removes all Z-coordinates where calculated Z-Compensation would be greater than the specified threshold.
Intensity values are not removed.

Interpolation:

If threshold parameter is set and points are removed, empty areas can be interpolated by using neighboring points.
Interpolation can be enabled with this parameter.

2.8 Example Multi-Scan Use Cases

2.8.1 Multiple XYZ Scans

This section describes how to carry out multiple XYX scans one after another.

Note:

The Z scan is only available for the U_XYZ

model.

Proceed as follows:

1.

Select the

Recipes

tab.

2.

Select

Add

in the

Scanning Jobs

area.

The

Add a new job

screen is opened:

3.

Add the desired jobs.

You can add as many jobs as you need.

To combine the jobs, they must be within the Master area.
