PT-140a (pirani) is off scale again, after more adjustments to pot this morning by Gerardo. It was working for a while today, reading in -4 Torr range and the CC was ON. I'm reopening FRS ticket 6061 so Richard et al can look at wiring.

Noticed that when I turn CC on the pirani reading drops from 1e-3 Torr to 5e-4 Torr.

Note that when we powered down PT-110a (on HAM6) we noticed a change in PT-140a.
