5.7.7.5 Testing Illumination Settings
You can set the illumination parameters by calling the ’Illumination’ option (see Section 5.6.4.8, Page 5 - 101).
Using the 'Measure Component Option' you can then measure the component and check your settings with
the aid of the measurement results.
Proceed as follows to test your illumination setting:
Using the illumination values suggested in Figures 5.7.9 or 5.7.10 carry out measurement. Measurement
should run through successfully.
For each level reduce the set brightness level by 50 %.
Measurement should run through successfully.
For each level raise the set brightness level by 50 %.
Measurement should run through successfully.
If you are not successful with the above procedure, proceed as follows:
Starting with the suggested illumination value, increase the brightness of each individual illumination level
for as long as measurement is still successful.
Find this upper limit value for each individual illumination level in turn.
Starting with the suggested illumination value, decrease the brightness of each individual illumination level
for as long as measurement is still successful. Find this lower limit value for each individual illumination
level in turn.
Determine the average value of the upper and lower limit values. This will be the optimum illumination
value.
Example of an illumination test:
– Settings from the diagram:
flat: 170
middle: 60
steep: 5
– Measure the component. Measurement is successful.
– Reduce setting values by 50%.
flat: 85
middle: 30
steep: 2
– Increase setting values by 50%.
flat: 255
middle: 90
steep: 8
– Measure the component. Measurement is successful.
– Reset the settings to the suggested values:
flat: 170
middle: 60
steep: 5
¬ optimum setting
