keyword=Left Dipole NMR
NMR compensating coil problem appears to have started during recovery from Tuesday's shutdown. Magnet current looks very stable from Last Friday (when I was here and know the signal was good) through Tuesday. Then there was a significant shift upwards (0.05 amps) Wednesday through this morning. My adjustments noted earlier brought the current back down. (In fact it's now lower than it was on Monday, but that can be due to hysteresis effects)
The effect should be small but data analyzers should take note!
