Zero shift calibration
This sensitivity setting performs the zero shift function and basic calibration (two-point
calibration / maximum sensitivity calibration / full auto calibration) simultaneously.
The lower of the received light intensity values specified at the time of sensitivity
setting will automatically be set to "0".
The light intensity received with a workpiece present will be applied with
the same amount of correction as for that received with no workpiece.
The following basic calibrations can be set while in the zero shift calibration.
• Two-point calibration
• Maximum sensitivity calibration
• Full auto calibration
If two-point calibration is performed with a reflective model when the light
intensity received with a workpiece is "2500" and without a workpiece is
"500":

The light intensity received
with no workpiece is
subtracted from the whole. The state with no
workpiece (the lowest of
received light intensity) is
set to "0".
