ASTM Noise Test

[cyclohexane]

I just changed out my deuterium lamp on an Agilent 1100 series HPLC. Right before I changed this lamp, I did the DAD self-test, and discovered failing results from the 20 minutes ASTM noise test. Now, I went to do the DAD self-test again, but now once it runs through the self-test (which are all passing), it just says the self test is finished without running the very last test, the 20 min. ASTM noise test. What am I missing? I do have it checked in the dialog box as well, so I don't understand why it is doing this.

ıf you change a deuterıum lamp, you would wait to lamp energy about 1 hour. When ı changed deuterıum lamp ı did a lamp calibration automatically in chemstation software.

Did you accidentally press "Skip all remaining tests" just before the last one?
