I looked at the Left Dipole NMR meter. The compensating coil power supply appears to be functioning OK. I see the current going up and down with the set voltage, at about the right values. I could manually get a lock signal, albeit a small one, that seemed to persist for a while. What I did notice was that the record HacL_D1_NMR:SIGLCK did not seem to reflect the state of the NMR meter. Although the meter was locked in, the GUI showed a "S". I'm not sure what this means, if anything. I did have the software regulator on for about 10 minutes, but that didn't seem to do anything. The best signal I could get was with the "C" probe, DAC was 2120, Comp. Coils were 6.500 volts, "MAN", "POS", "OFF", 1.338963T. Higher and lower values of the Comp. Coils voltage killed the small lock signal that was there. I was not able to get a lock with the "F" probe, for the little amount that I tried.
