Dear isogeochemists,

I was running a Delta Plus with the old NT 1.5  software.  Some days back I changed the computer and the National Instruments interface and installed the new software 2.0 (with service pack 2.62). Everything is working nicely except the peak center is not working correctly in case I introduce standard gas from the bellows (continuous flow mode: I have a TC connected to the Delta Plus and I am using the bellows for the CO standard gas). Introducing std.gas by the Conflo is no problem and works without any problem. 


When defining the method, I choose the following:


1st page of the method:

Acqusition_old.isl (otherwise the program will close the valve to the below)


Ref on: change over right.sct

Ref off: change over close. sct. 


This worked nicely with the old software, however, now with the new software, the changeover does not react. I tried it with several methods, the changeover valves do not switch 

Has this been seen before? Did anything change in comparison to Isodat 1.5

Any advice is highly appreciated.


Thank you


Michael Joachimski
