Hello,
LS-335 (ST -500 Cryostat) temperature controller is showing S. OVER when temperature goes below 70-80 kelvin while the cooling temperature is set to 4.2 kelvin. Previously it was not the case but from last some days it starts showing like this. Can you suggest me the possible solution?
Sensor: DT-670 Silicon diode.
Excitation current: 10uA
Thank you.
