6.7.7.5 Testing Illumination Settings
You can set the illumination parameters by calling the ’Illumination’ option (see Section 6.6.4.8 on
page 325
). Using the ’Measure Component Option’ on page 311 you can then measure the com-
ponent and check your settings with the aid of the measurement results. 6
Proceed as follows to test your illumination setting: 6
Å Using the illumination values suggested in Figures 6.7 - 9 or 6.7 - 10 carry out measurement.
Measurement should run through successfully.
Å For each level reduce the set brightness level by 50 %.
Measurement should run through successfully.
Å 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: 6
Å Starting with the suggested illumination value, increase the brightness of each individual illu-
mination level for as long as measurement is still successful.
Å Find this upper limit value for each individual illumination level in turn.
Å Starting with the suggested illumination value, decrease the brightness of each individual illu-
mination level for as long as measurement is still successful. Find this lower limit value for each
individual illumination level in turn.
Å Determine the average value of the upper and lower limit values. This will be the optimum illu-
mination value.
