Percentage calibration
A setting value is established with a percentage in respect to the current received light
intensity. When used together with external calibration input, percentage calibration
can be performed from an external device, such as a PLC, allowing highly accurate
detection of transparent workpieces and small workpieces, etc.
Refer to "Sensitivity Setting" (page 4-4) for details.
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.
Refer to "Sensitivity Setting" (page 4-4) for details.
Percentage calibration and zero shift calibration cannot be set with
channel 2 of the 2-output type models.
