Hello,

Just installed the source of Delta V after cleaning it and putting in a new 
filament.  After vacuum reached 5e-07 I turned on the source and am getting 
a 1.5 mA current for both Trap and Box.  I cleaned our Delta Plus source 
previous to this one and everything was fine, I am used to seeing 
either .7/0.78 when everything is working well or 1.5 and 0 when its a bad 
filament etc.  What is happening, any help is greatly appreciated.  Thanks.

Best Regards,
