Setting Measurement Conditions (Expert Menu)
Setting Calibration
Calibrations can be set to compensate for differences between measurement values and actual
dimensions due to the color or material of the measurement workpiece.The setting method varies
depending on the measurement item set for the output.
When calibration is executed, the span and offset will be set automatically. It is also possible to make
adjustment using [Output].
It is not possible to execute calibration for the following measurement items: Angle, Area, Arithmetic average
roughness, and Define. Adjust the span and offset using [Output].

Compensating for Measured Height and Position
To compensate for the error, perform the measurement twice.
Applicable measurement items: Height, Edge position, Edge center, and Peak/bottom
Example 1: In case of [Height]
Height of the workpiece: 10 mm
Compensate for a measured value of 9.95 mm, such that it is registered as 10 mm.
