CAUTION:
To ensure optimal performance of the PosiTector
DPM L probe, do not obstruct the airflow near the air temperature
and humidity sensors. Keep fingers away from the sensor, as body
heat can influence readings. Allow time for the probe to acclimate
and for the readings to stabilize when moving the probe between
different environments. When attaching a probe to the surface, do
not use excessive downward force, and do not drag it sideways.
When not in use, place the probe into the protective plastic case to
prevent damage.
