Sorry my fault not telling that this is a Bruker AQR/P Spectrospin 300 complete previously working NMR machine. Just ran out of the helium. They had to turn the magnet off (hopefully according to the proper procedure).

Putting brieflly what I have understood so far is after filling N2 and He I should:
1- Connect the power supply to the magnet ports on the top of Spectrospin tank 2- Turn on the magnet persistent switch heater 3- Program the powersupply for about 0.2A / min and turn it on 4- After magnet current reached the maximum set current (about 100A) turn off persisten switch heater 5- Turn down power supply current to zero gradually and turn it off at zero 6- disconnect power supply
I need more detail explanation on these items and in case if I have missed anything here? A video showing the procedure could be lot better.
