Howard and I took the NMR from the Right Arm and installed it on the Left Arm. We found the unit we just got back from repair was not working correctly. Perhaps we missed something and it is just a switch setting, but I do not think so. This leaves us with only one working NMR readout. The software regulator requires the NMR meter to run. The power supply will still work, but drift can be an issue. Our two new units do not come for quite a while. We will take another look at the "spare" unit tomorrow.
