We are still working on updates both the software and the cRIO. At some point today we need to reboot the Gas Shed cRIO and maybe the Forward Carriage. Please let us know it is ok for testing and rebooting.

In addition while you are working out the C4F10 transfer line issues, I wanted to confirm with you that this issue is just localized to part of the system outside of the Hall. Morgan and I discussed the issue of the gas condensing last week and he informed
me that the gas is warmed up enough by the time it gets to the hall to not be an issue with the MFCs (ie...last winter's MVT problems).</div>

Looking at the flow data from the weekend, both sectors low pressure set points were set to 1.3 iwc (in the afternoon on 2/1), S3 has flowed for 13:20 (min) at 1 L/m. S5 has flowed for 2:19 (min) at 1 L/m. The C4F10 Return has flowed for 5 minutes at 2 L/m,
as the pressure in S5 exceed 2.5 iwc early (01:46 am) today. <br>

Please let me know when the scale will be re-zeroed so that it can be tracked as well.

Hi Marc,<br class="">
<br class="">
Can you provide a graph of the supply pressure and scale weight from Friday to Monday please? Throw in outside temperature also.<br class="">
<br class="">
We are having an issue with c4 F10 condensing in the transfer lines.<br class="">
<br class="">
Thanks,<br class="">
