* As you get close to that value, the oscilloscope will show the NMR resonance. Keep moving until the resonance is well centered. At that point, your dipole is set to the desired field | * As you get close to that value, the oscilloscope will show the NMR resonance. Keep moving until the resonance is well centered.

* Set EPICS channel **I265DS_MAG.BSET** to 13.5454 (note, the default value of this channel is always an (impossible) 9999.1111, which is ignored. Typing 13.5454 will cause the magnet to go to 257.577 A, and **I265DS_MAG.BSET** goes back to 9999.1111. Setting the magnet this way will get you to plus or minus half a percent of where you want to be. | * Set EPICS channel **I265DS_MAG.BSET** to 13.5454 (note, the default value of this channel is always an (impossible) 9999.1111, which is ignored.
