Calibration Function
When there is difference between the internal measurement value (R.V.) and the actual
dimension of the object, the value can be corrected. There are two correction methods as
below: One-point calibration and Two-point calibration
One-point calibration
Only tilt (span) is corrected while the zero point (offset) is not corrected.
Two-point calibration
Both the zero point (offset) and the tilt (span) are corrected.
Note
• If the following conditions are not satisfied, the screen below is
displayed when the setting is complete. Make the setting again.
For one-point calibration
For two-point calibration

• If the measurement mode is set to the "Pin interval judgment mode"
or "Pin diameter judgment mode", the calibration function cannot be
used. Only "Standard" and "User setting" can be switched on the
setting screen.
