Hi Mark
the shift of the resonance is proportional to the quality factor of the probes.
The higher the Q the worse it gets. So Prodigy probes will be affected but
not a much as helium probes.
The measured and corrected values refer tot he reading at the thermocouple
and a corrected value that is based on a correction that is entered by the
user. The correction is varying from probe to probe and is also dependent
on other factors such as airflow. The correction is a linear correction and
can only give a good fit over a limited range of maybe 30 - 40 degrees as
the large dependence of shift vs temperature is not linear

Hi Everone,
Does the issue with Ethylene Glycol also apply to N2 cryoprobes (e.g. Prodigy)
or is it mainly Helium cryoprobes? Also, under 'edte' there's a measured value
and a corrected value. Does anyone know how good the correction is in general,
or does it vary from probe to probe?
Thanks,
Mark
