Make logic calibration settings as explained below.
Setting Range
Logic calibration does not require master workpieces. Input the non-calibrated values
and calibrated values of two measuring points (target 1 and target 2). Logic calibration
uses the following values.
T1-A: Target 1 display value before calibration
T1-B: Target 1 display value after calibration
T2-A: Target 2 display value before calibration
T2-B: Target 2 display value after calibration
Make settings so that the following conditions will be satisfied.
T1-A < T2-A and T1-B < T2-B
Furthermore, set the calibration span between 0.5 and 2.0.
