1610 IVC pressure 5.4E-3 mbar, which is confusingly below the best pressure scroll pump should be capable of according to the manual. Perhaps there is something I haven't considered.
Turn on 1 K pot pump to run extended test.
1755 With Matt's help, hooked up Little Blue's pump to IVC. IVC pressure is currently 2.5E-3 mbar.
2100 No problems witnessed with 1 K pot pump. Just to be safe, turn it off so nothing happens overnight.
IVC pressure 1.6E-3 mbar, which is a little higher than expected. Having said that, we are using a different turbo pump, so this may be acceptable.
