FH/FZ5 Processing Item Function Reference Manual
Circle Regression
Calculates the circle that generates the shortest total distance from multiple measurement coordinates (Circle
Regression).
Used in the Following Case
• This is used when calculating the center and radius of a circle.
Parameter Settings (Circle Regression)
1 Set each item in the "Parameter" area.
2 Click [OK].

Description
Method
• [Nearest unit]
•Calculation
Nearest unit: calculated from the unit da
ta of several continuous
coordinates that were just measured. The number of units
referenced is indicated by the Number of points. If a unit where
coordinate measurement is not performed is included in Nearest
unit, calculation will not be performed properly and measurement
will be NG.
Calculation: Calculated from expression set up.
Reference: When Calculation is Selected (p.631)
Number of points [3] to 8 Set up the number of coordinate poi
nt
s used for calculation.
Use in cases in which an approximate circle
is to be calculated from multiple measurement
coordinates.
