The values may be off by 2-3 mm which is the measurement noise. The 26m live page will have the receiver listed (left side)as "S/X" if all is well.</note> |

* **Cryogenics: Vacuum pressure less than 3.5**. The Vacuum pressure in the S/X dewar should be below this value (measured in microns of Mercury). If it increases above this value, it indicates a leak. Let Brett know. e.g. this readout indicates a vacuum pressure of 1.227 <code>2014.126.09:00:46.53/rx/17(pres),on,a,on,on,on,off,locked,1.227</code> | * **Cryogenics: Vacuum pressure less than 3.5**.
