Jack says "The scope shows the NMR on the Right Dipole is locked in. The field readback is all over the map. I think we have fried a NMR meter in some fashion. If someone knows of a quirk in the meter that would do this please call and let us know. The current readback is very stable. Perhaps it would be best to set the current and just run hoping that the current readback is as accurate as we need."
