Showing an error of 'Adjust Mass Axis failed : Delta is outside of tolerance level. Instrument has been vented for about
The instrument was shut down about a year ago but was working well prior to being shutdown. The tuning solution expires 8/2020, prior to being started up again we cleaned the nebulizer, capillary, and skimmer. I haven't checked the needle adjustment, we don't have the kit to do so in the lab at this time. The source is an ASJ ESI, vacuum is good running at about 8.9e-6 when in standby, with gas flow at 2.17e-5, which is what we were at prior to shutting down and same as when it was installed in 2015.
