Dear all:

I recently replaced the filament on my isoprime source, only to find that 
the source wouldnt come on when selected. After venting I did a thorough 
electrical conncetivity test on all pins right from the source housing 
through to those pins that connect to the electronics box. Ensuring that no 
connector were touching in and around the source itself I reattached the 
source flange and when the vacuum and pressures were at desired 
levels...again nothing. Souce Status: red bar, reading 255 changed to red 
bar reading 18.0 when source switched on. Perhaps there was a leak on the 
capilliaries from my ref box and EA so changed the union fitting here right 
before the NUPRO...no effect still reading 18 with a red bar. Assuming good 
connectivity and no leak (Hi Vac 4e-2 prior to source turn on) how can i 
resolve this problem

Cheers

Neil
