Key Points for Adjustment
Select the adjustment method referring to the following points.
When the measurement results are unstable
Measurement Results for Which Output Is Possible (Scan Edge Position)
The following values can be output using processing items related to results output. It is also possible to
reference measurement values from expressions and other processing units.
Parameter to be adjusted Remedy
Measurement
If the color of the edges to be detected is decided, spe
cify the color with [Edge color]. If results
are not stable even with the color specified, specify a larger value for the color variance range.
If noise is detected as an edge, specify larger valu
es
for "Noise level" and "Noise width".
