VACSTAT BSC3 single sensor glitch, no alarm issued to VAC team
At 19:27:26 PST a PT132_MOD2 glitch caused a single-sensor VACSTAT glitch. The new code requires two chambers to glitch before alarming the VAC team, so in this case no cell phone alarms were sent.
The glitch lasted 4 seconds, and as before it was DeltaP which tripped, exceeded its trip level of 1.0e-08Torr (see attached).
I restarted vacstat_ioc.service on cdsioc0 to reset the system.

Attached trend shows the increase in sensitity for BSC2's slope and deltap following the BSC3 glitch detection. All trip levels were later restored following a restart of vacstat_ioc.
