In the [Calibration data] area, confirm the
modification made.
Compensate the calibration result
The calibration result can be compensated by setting the compensation amounts such as magnification ratios
and offsets for the actual dimensions and actual coordinates.
1
Set the compensation values in the
[Parameter] area.

In the [Calibration data] area, confirm the compensation result.
Note
The following relational expressions can be made for calibration parameters and compensation values. Be careful
about the relationships between the pre-compensation and post-compensation parameters when adjusting
parameters.
Before adjustment: A1, B1, C1, D1, E1, F1
After adjustment: A2, B2, C2, D2, E2, F2
Compensation ratio X: KX, Compensation ratio Y: KY
Compensation angle X: θX, Compensation angle Y: θY
X origin offset setting: OX
Y origin offset setting: OY
• A2 = KX × (A1 × cosθX - D1 × sinθX)
• B2 = KY × (B1 × cosθY - E1 × sinθY)
• C2 = C1 - OX
• D2 = KX × (A1 × sinθX + D1 × cosθX)
• E2 = KY × (B1 × sinθY + E1 × cosθY)
• F2 = F1 - OY
