All Cernoxes are reading a normal temperature value now.</div><br><div>From the LabVIEW latching indicators, the Cernox TR817D3HB1 in LV Chassis 3 was the sensor that jumped to 325 K. However, I cannot find in MyaViewer where that Cernox or any Cernox read 325 K recently. <br></div><br><div>Since there is only Brian's subVI that targets a fixed voltage for Cernox excitations, it seems that just using a fixed target voltage allows a Cernox to automatically recover if it jumps to 325 K.<br></div><br><div>Despite the fixed voltage allowing the Cernox to recover, it might be a good idea to continue monitoring the Cernoxes to observe another instance of a Cernox automatically recovering that is recorded in MyaViewer before closing the 325 K error investigation.<br></div><br><div>Best regards,<br></div><div>Tyler</div></div><br></div></div><br>_______________________________________________<br>Dsg-hallb_magnets mailing list<br>Dsg-hallb_magnets@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-hallb_magnets<br></div></div></body></html>
