5.2.3 Color Test Using the Function Elements of the Start Screen
After all required settings have been made using the
Configuration
window, you must now find the correct
test mode and the correct checkpoint settings for your application.
i
We recommend testing with largest possible light intensity.
The intensity refers to the originally tested RGB values of the color chip, see Fig. 23 . The value for the light
intensity should be between 30 % and 80 %.
This prevents the color chip operating outside the linear sensitivity function in relation to the color param-
eters. An optimum test result is thus achieved.
Now, note the following steps:
First select the required checkpoint / required color chip.
Now start your test with a sensor range of 9x9 and a large exposure time.
Reduce the exposure time in the next steps while you are in the light intensity range 10 % to 80 % .
If the reduction of the exposure time is not sufficient, change the color chip range from 9x9 to 3x3 and
repeat the determination of the optimum exposure time as described above.
If you have an application in which you test several LEDs per test, we recommend determination of the opti-
mum setting for each checkpoint / each color chip using the main screen.
Using the pop-up menu
Test
, now change to the window
Measurement settings
and
Measure-
ments, see Chap. 5.2.4 .
The settings for the exposure time and sensor range are adopted here.
In the case of an application with several LEDs with the same light intensity, it is sufficient to determine the
setting of the color chip range for one LED in this way. Afterwards, this setting can be transferred to the other
checkpoints / color chips using the
Measurements
window, see Chap. 5.2.4 .
