Convectron gauge check:

Brand new 10 years old convectron gauge at atm was swapped into the place of existing gauges to see if they read close to 760 Torrs

They did reasonable well at the low end. I tried to imitate calibration and bring down the high end with little success.

( P1 and P2  were reading 7e-4 to ~660 Torr  The correction of the upper end pushed up the lower end too. I will correct this later

P3 and P4 high ends are way off )

The point is that they work.  Convectron gauges will be replaced and calibrated at the next vent.

Interlocks were not triggered during this test. I was expected to close the PSL shutter when P1 was reading 760 Torr

This hide some problem or  not understanding.

It was good to see CC1 and CC4 working at the moment

Somehow I succeded opening VM1 and closed VM2 = vacuum normal

I just hope it stays open overnight to get comparable RGA scan.
