Hi Tyler,

I am still investigating and looking into why this is happening at all. 
When the magnet was warmed up to 80K, none of the sensors went to 325 K.

Would it be possible to set constant current values for I1 and I2 (500 
nA and 250 nA)? I would like to see, if it is happening because we are 
varying the current based on power dissipation or not. Please let me 
know, if you need more information

Thanks,

Rama
