■ Emitted Light Intensity Search
This function searches the received light intensity of a measurement
surface and sets the appropriate emitted light intensity automatically.
Set this function when measuring the thickness of a transparent object with low
received light. Without this function, “Emission Adjustment” function
automatically optimizes the emitted light intensity based on another objects or
surfaces with high received light. This results in failure of optimizing the
emitted light intensity for any low-reflectance objects. This function is useful
for measuring the setting surfaces at “Output Selection”.
To optimize the received light intensity of an object with the least light
intensity among the all setting received light surfaces at “Output Selection”,
determine the emitted light intensity of it from the fixed value of 31 levels
and change the setting.
After the completion of “Emitted Light Intensity Search”, the optimum value
will be displayed within “0.04% fixed to 100% fixed” . If the search is
failed, “Emission Adjustment” is set to “AUTO” .
When changing the initial setting of “Output Selection”, perform it before
starting the emitted light intensity search.
Refer to “4-3-2 OUT Setting”-
“Output Selection”.
This searches the emission intensity in all areas regardless of the setting of
emission adjustment area.
● How to use
1
Display the “Emitted LI Search” screen.
2
Touch the Execute key to execute the
“Emitted LI Search”.
The right screen appears during emitted light
intensity search. After the completion of the search,
the below screens appears depending on the result.
3
Touch OK key.
The start screen of the step 1 appears again. On the screen, the current
“Emission Adjustment” value can be confirmed.
When the search has been failed, the “Emission Adjustment” is set to
“AUTO” .
When Search was completed. When search was failed.
