Greetings:
Strange gremlins today:
Column Chamber valve is opening and closing at random times.
EHT gun trip error 519 sensed as pressure in gun section exceeds > 5.0e-009
GUN restarted and allowing to stabilize.
Pico ammeter reading unstable and very noisy.
Checking on power to the system for signals -- after lunch.
Strange very stange...
