PT8565 and 8563 are reading 2.3 atm and a bit above what would be ideal but I think it is real and accurate. The pressure in that leg of the circuit is a bit higher than ideal. It could be released but has not been a problem and we can run with gas in the circuit.

PT8561 being 1.5 atm is OK and is likely because ESR has shut the warm helium to the Hall. We can run like this but to warm up or purge targets the warm helium supply valve will need to be opened.

This looks to be a real failure of some sort. note 2248lb is 1000kg and may be the maximum of the load cell. I don't think it is real because no other Z force sensors have increased. Could it be a broken wire or a malfunction of the controller? I'm not concerned
about running with it not reading properly (which has been 0.0).</div>
