To ensure optimal performance of your PosiTector DPM, do not
obstruct the airflow near the air temperature and humidity sensors.
Keep fingers away from the sensor, as body heat can cause
incorrect readings. Allow time for the instrument to acclimate and
for the readings to stabilize when moving the instrument between
different environments.
When using the surface temperature probe, do not use excessive
downward force, and do not drag it sideways. When the instrument
is not in use, place the rubber cap over the surface temperature
sensor to prevent damage.
CAUTION:
