Wang,
I think you need to check the configuration. May be you have a wrong thermocouple checked.

Subject: AMMRL:Temperature controll problem with topspin
Dear All
We have Bruker Avance II 600 MHz instrument with
Cryoprobe running by 1.3 topspin. Currently, I have a
problem for the temperature controll because the
heater is off automatically with the meaasge "can not
determine the BVT model, no error". The instrument got
back to work about a week after Bruker engineer
replaced the old BVT 3200 unit even the message
continued to appear. Does anyone have samilar problem
to share this experience with me? Thanks in advance!
Tianzhi Wang
