【Mechanical Compensation】 When checked, the compensation value will be converted to mechanical data and added to the output result. (Requires connecting calibration when checked)
When **Mechanical Compensation** is not checked, the compensation amount is pixel compensation, added to the output. When Mechanical Compensation is checked, the compensation input is a mechanical point, requiring calibration to convert the compensation into image points and add them to the output.
