Hello,
I have a problem which pops up randomly where the Model 370 AC Resistance Bridge (with Model 3716/L 16-Channel Scanners) that is used to read the temperature sensors of a dilution fridge stops reading one or more channels. The real issue is that it is not possible to reactivate the channel without switching the resistance bridge off and on again (and even that is not a guarantee), which means that the fridge has to be warmed up.
Has anyone got experience of similarly buggy behaviour with reading of channels? Is there some way to force a channel re-initialisation? Could there be a firmware issue?
I realise that the fridge software is a potential culprit also, but it is not giving an "off" command per se. I am continuing to investigate that avenue, but some Lakeshore help in the meantime would be warmly received!
Usually it is one channel being consistently inaccessible. However, I've attached a picture of the worst case so far where initially one channel was affected and then all the channels were switching on and off wildly.
