After a firmware upgrade to our SLCB board it seems to have lost it's
helium calibration. It's seem back in the dark ages this was done with
calibration box where you dialed in resistances for full and empty. Alas,
we don't have this box.
We do however know the resistances and get hold of a potentiometer. Does
anyone know how this might be done? I also do not know the pin out of the
sensor plug.
I'm attaching the Oxford magnet helium calibration document and the SLCB
board calibration document...
We have a Blue and Black plug for another system with a Bruker magnet. I
would assume we could use the black plug/shunt to be the short in this case
also?
Thanks,
