Resuming pumping of PT180
1120 - 1125 hrs. local -> Kyle in and out of the LVEA 
1135 - 1140 hrs. local -> Kyle in and out of the LVEA 

Valved-in locally mounted turbo to PT180. Should know in a day or two if the indicated pressure value will "drift" up while the gauge is pumped by the turbo and not exposed to the site vacuum volume.  

Also, I witnessed the truck driver decouple and store the transfer line following the LN2 delivery to CP3.  He installed a plug to, at least, one end of the transfer line before storing it - I assume the other end was also plugged.  

Cylinder pressure of UHP N2 bottle holding pressure to CP4's clogged sensing line is @ 1500 psi while the flow meter indicates no flow.  The regulator output is set for 20 psi and the flow meter is limited to 0.4 LPM.
