I resumed the pumping today. Now the pressure is 0.48 torr. The pump was stopped.
I resumed the pumping from 19:00.
Now the valve RV1 is full open. But the pumping is really slow as we are using only one RP.
After 3hrs of pumping, P1 reached 1.2mmtorr but still we need 2hrs of pumping...
I stopped pumping at 22:30.
