It would be nice, but it likely unnecessary. The calibrations need to
be done only at the start of the data collection and then at the end,
to establish the end points. The collected data plots how it varies
day to day, and the general trend.
Sorry, last message sent prematurely.
Also, in setting the environment, its not necessary to complicate
calculations and let it swing to extremes. So keeping the reference
in a temperature controlled room set by an ordinary air conditioner
is enough to reduce swings in relative humidity and temperature, but
not control it. This leaves barometric pressure as the largest variable.
