Hi Everyone,
On our AVANCE 500, we have a BVT3200 and a type T sensor for
temperature control. We do not have a BCU05 or a N2 supply and
so RT air is feeding our probes. We have been running all
experiments at 300K whereas our room temperature is at 293K.
Performing an edte self-tune on our probes under these conditions
leads to a heater current which never strays too far from 0 and,
what's worse, oscillates and sometimes goes to zero. This can
wreak havoc on our lock signal and so I'd love to get the heater
stabilized.
So my question is, short of buying a BCU05 or running everything at
even higher temperatures, are there any ideas to stabilize our
heater output?
Thanks For Your Help!
Mike
