The noise removal flow is explained by using a sample case that the required minimum points is 2 points, and that the allowable error is 10.0.

The maximum distance between
the reference position and the
measured position is calculated.
Then it is compared to the

Note
• Only specified movement axis or exist axial direction are applied to set in the case of X, Y, Xθ, Yθ, θX and θY
stages. Not exist axial direction is not displayed.

to the permissible error.
Description
This means the available mark number after the noise point
removal. For example, when you need minimum 3 points
for positioning and set 4 as a number of points in "Position
setting" area, maximum 1 point could be removed as a
noise.
Set allowable error (distance of measurement position and
reference position) is set. Calibrate by removing the noise
points repeatedly until the required minimum number of
points is reached.
If you set the Error tolerance to 0.0000, all of the points are
calculated and the result with the smallest error value is
output.
Alignment by 2 points
If the maximum error is still larger than the
permissible error, 2 point positioning is
executed. This is final step because
minimum 2 points is required for this
positioning.
