Here's one for your memory banks. I have a Beckman System Gold HPLC with 126 pumps and a 167 detector plus a 406 data module. The System Gold software is version 3.10. I enter an end time for the run in the pump control method but the run won't stop at the entered time. I always have to end the run manually. Any ideas? What am I missing?

I figured it out! The 167 detector does not have a time program to end the run so you have to use relay #5 in the pump time program to stop the data at the end of the run. I found this by going back to one of the original instrument methods but I haven't found this anywhere in the manual.
