PT-140
Gerardo, Chandra On Tuesday, Aug. 23rd, we adjusted potentiometer on PT-140a (pirani) again - this time CCW 11 turns. Since Gerardo terminated cables for AIPs, gauge voltage has changed again and needs to be adjusted again so CC does not keep tripping due to set point interlock.
One more adjustment to the potentiometer since the CC interlock tripped a couple of times since the last change. 6 more turns CCW.
