Measurement Parameters (Scan Edge Widths)

Measurement parameters can be changed as needed to address unstable measurement results.Normally, the factory default value will be used.

After changing a setting, check whether measurement can be done properly by performing an actual measurement.

In the Item Tab area, tap [Measurement].
The edge profile of the measurement region is displayed as a graph in the Image Display area.

Set the value of each item in the "Display area" area.

Setting item		Set value [factory default]	Description
Display area No.		[0] to 99	This item uses the scan region of which edge profile is displayed.
	Enabled	[Checked] Unchecked	Specify enable/disable of the divided area.When disabled (unchecked) is specified, measurement is not performed.
		[Forward area] Reverse area	Forward area: The edge is searched from the start point of the area toward the end point. Reverse area: The edge is searched from the end point of the area toward the start point.

Set the value of each item in the "Measurement" area.

For color cameras:

Setting item	Set value [factory default]	Description
Edge level	Position (%) for width of a color 0 to 100 [50] Value of color 0 to 442 [20]	Select a color difference level with which the edge is detected. See "User's Manual", "Edge level"
Edge color level	0 to 442 [100]	This emphasis level can be specified only if the edge color to detect is specified.

For monochrome cameras:

Setting item	Set value [factory default]	Description
Measure type	[Projection] Derivation	This sets the type of edge measurement.
Density change	[Light→Dark] Dark→Light	Select whether a black-to-white change or a white-to-black change should be recognized as a density change in the specified region.
Edge level	Position (%) for width of a density 0 to 100 [50] Value of density 0 to 255 [20]	Select the density change level to be detected as edges. See "User's Manual", "Edge level"

If necessary, set each item in the "Noise removal" area.

Setting item	Set value [factory default]	Description
Noise level	0 to 442 [5]	When detection is affected by noise, increase this value. See "User's Manual", "Noise level"
Noise width	0 to 9999 [0]	Set the width for judging noise. When detection is affected by noise, increase this value. See "User's Manual", "Noise width"
