SOLUTION:
Your sample temperature is too high for the instrument to equili-
brate with it in a reasonable amount of time. The instrument and
sample need to be in temperature equilibrium before accurate mea-
surements can be made. Therefore, very cold samples will take a very
long time to measure for the same reason. To avoid this problem,
make sure to only measure samples that are at the same temperature
as the instrument.
