I am trying to operate a 6890n GC with the help of an operator that knows how to start a measure. The system consist of both the GC and the detector unit, as well as a Windows NT where the software exist to control it. We are able to start a measure by booting the system and applying a name to the job like example.d Then we can start the system after heat is right and we can see the detector acquire data with the name we specified, we can also see 2 signals live in the swoftware but the ion and spectrum is not updating. This is confirmed in the end by a error message saying that "Neither GC nor MS Data collected; consult logbook". The GC Signal 1 and 2 updates, but not the Total ion and spectrum. I have two problems at least. in the data directory after the run I cannot see any run.log that seems to be the logbook so I am not able to debug och look for what is wrong. Also it appears as if there is signal missing somehow. I am not sure if the signal comes from the detector unit or directly from GC, the thing is that on the back I have 3 special connectors, one is called Sampler 1, the other Sampler 2 and one is Tray. There is cable in the Sampler 1, but not Sampler 2, and the Tray is connected to , well the tray of course. Is both the Sampler connectors suppose to be connected, and if so where? I have not been able to find is the Sampler 2 is required, we do not have a cable for it and it was acquired "as is" and so it has been running before.
How can I find out why we are not getting the Ion and Spectrum signals? What am I missing?
I know these are old things but I am comfortable with the NT system and knows about the equipment from a engineering point of view, I do not know how to debug/find problems in such a system and I have no log file to inspect.
