10. ADMINISTRATOR MODE
10.5.6 Digital
Each ROI has its own measurement result, either positive (pass, OK, condition were met) or negative (fail, NOK
condition were not met). This depends on meeting all previously set conditions for each ROI separately.
Here administrator can select the digital output logic. There are seven digital outputs, each with either low or
high signal. This signal is deduced out of the individual ROI measurement results.
The boolean logic is used to calculate the digital output among selected ROIs. If there is just one ROI checked
for the digital output, the measurement result will apply directly to the digital output. If there are more ROIs
checked for one digital output, the final result (positive or negative) is calculated with the boolean operations
AND, NAND, OR, NOR.
Figure 10.12: Possible digital output settings.
This is the short summary of boolean operators:
AND
‐ Positive only if all measurement results of checked ROIs positive
NAND
‐ Opposite of AND, negative only if all measurement results of checked ROIs positive
OR
‐ Positive if at least one measurement results of checked ROIs positive
NOR
‐ Opposite of NOR, positive only if all measurement results of checked ROIs negative
