Autotune Specifications for 7900 ICP-MS

I am trying to find information on setting specifications for the autotunes for He and H2 modes for a 7900 ICP-MS. I have found specifications from agilent for the no gas mode. I am trying to figure out what type of results I should be getting in the He/H2 modes during the system auto-tune to make sure the system is running properly before use and if settings need to be adjusted. Agilent states that this is typically determined by the user, so how have other people determined these specifications?
