Hi Volker, The PR sumitted: https://misportal.jlab.org/reqs/pr/viewPrSignatures.do?prNum=381117 is for replacing the currently failing display for the DC R1-2 Return H2O. After troubleshooting we found that the sensor and local display are okay, but the unit isn't sending the proper voltage out to the cRIO which means the reading in EPICS is bad. Thanks
