Key Points for Adjustment

Select the adjustment method referring to the following points.

When the measurement results are unstable

Noise is detected as defects.

Parameter to be adjusted	Remedy
Measurement parameter	Specify a larger value for "Defect judgement" in the judgement conditions.

Judgement will be NG.

Parameter to be adjusted	Remedy
Measurement parameter	Make the measurement region larger than the value of the element size.

When the processing speed is slow

Parameter to be adjusted	Remedy
Measurement parameter	Specify a larger value for the element creation interval.
