Note 1. Exponential expressions are used for numbers larger than 9999999.999 and smaller than –999999.9.
2. The number of measurement items is up to 5, but only one window number can be read.
3. The ranges of measurement values are as follows:
For calibration OFF setting :–2147483.648 to 2147483.648
For calibration ON setting : –9999999.999 to 9999999.999
4. The priority of measurement items being output are as follows:
Area
Center of gravity X, Center of gravity Y
Displacement in center of gravity X (reserved), displacement in center of gravity Y (reserved)
Main axis angle
Main axis angle displacement (reserved)
Edge angle
Edge angle(reserved)
Center X, center Y
Center X displacement (reserved), center Y displacement (reserved)
Inclination
Inclination displacement (reserved)
Intersecting point X, intersecting point Y
Intersecting point X displacement (reserved), intersecting point Y displacement (reserved)
Reference Object Registration Command 1 Execution (F300)
(Sequence No. 463)
This sequence performs a measurement for the input image and updates reference object data of the full window.
