display.
If dust is present
then sharp spikes
will be observed.
Measurement runs
with dust present will
be removed from the
final measurement
calculation by a dust
filtration algorithm.
A wildly fluctuating
count rate may
indicate that thermal
gradients are
present in the
sample, and further
time is required for
temperature
equilibration.
