■ Emission Adjustment Area
This function specifies an emission auto adjustment area. The light
intensity feedback function operates between the two cells from starting
cell to ending cell.
In case of measuring a transparent object where the high reflectance in the
surrounding affects the emission, it is possible to adjust the emission on
the beam receiving surface you wish to detect by specifying an emission
adjustment area.
Emission Adjustment Area specifies two light receiving cells of Area-a and
Area-b. The light intensity feedback function works so that the light
received intensity is optimal among the specified areas. Area-a and Area-b
are set in the range from 1 to 512 respectively.
・
This is valid when Emission Adjustment is selected as “Auto”.
・
In case
the sampling cycle is set to 10 μs, set Area-a and Area-b in the range
of 1 to 112 respectively.
・
In case
the sampling cycle is set to 20 μs, set Area-a and Area-b in the range
of 1 to 256 respectively.
・
The magnitude relation between Area-a and Area-b is automatically
determined by the controller. However, do not set the two to the same
value.
・
In case the setting range of the specified area is not appropriate, light will be
emitted at 100% fixed and measurement alarm will go off.
