Hello,
I’ve been following the notes of our previous technician to perform the
liquid helium fill when our probe reading is around 100. I also found the
attached helium probe calibration chart, and I’m wondering if I’m
performing the helium fill prematurely. Does the digital readout value on
the probe refer to the “Probe reading (mm)” column or the “He level
in can (mm)” value? Should I be waiting a little longer before the fill?
Thank you!
