A typical screen is shown below.
The lower part of the screen indicates in real time what tasks the Brewer is performing, and there is
a Status Box which shows some important status information including:
-
the latest DUV measurement
-
the running average O
-
the latest SL " R6 " value
-
the latest HG measurement time and temperature
-
the current temperature
If the software has crashed, then an error and a program line number will be displayed on the
screen.
A glance at the screen will determine if the Brewer is operating as expected, and any discrepancies
should be noted and corrected.
END OF DAY PRINTOUT
Look at the End of Day printout (or "D" file if PD is used in ED) and check especially the
diagnostic tests, and summary data.
1. HG SUMMARY
There should be no errors printed which might indicate a Micrometer positioning problems.
Check that there are no (or few) cases where it appears that the HG required multiple
attempts do complete a successful calibration.
Note the Intensity and watch for trends in intensity increasing or decreasing.
2. SL SUMMARY
Note the R5 and R6 ratios and the F1 intensity, and watch especially for sudden changes that
could indicate a malfunction.
Gradual changes over time are to be expected.
Make a plot (or plot the SLOAVG) file every week or two to look for deviations from the norm
of the three parameters.
Changes in R5 and R6 are associated with changes in the Brewer performance which could
be reflected in errors in the O
