						I switched to a splitless pressure pulse inlet and after chemstation loaded method to GC, this error message appeared. When I ran the method, the error cleared. How do I check the GC to make sure the pressure pulse is being used. The display on he GC inlet showed splitless pulse pressure and the parameters of the method is identical to the GC's. Thanks.

						One way would be to set up the second data channel to monitor the inlet pressure.  Or, to keep it simple, watch the inlet pressure reading on the instrument during an injection.  You should see it increase and decrease.
