DeFelsko POSITECTOR DPM Full Manual page 11

The Magnetic Surface Temperature Sensor can be disconnected
from the K-Type thermocouple connector (DPM-S model only) and
replaced with one of the following optional sensors:
Hand-held Surface Temperature Probe
- for spot checking hard-to-reach surfaces
Self-adhering Surface Temperature Probe
- sticks to solid materials including aluminum, wood, concrete,
etc. Ideal for unattended monitoring.
Liquid Temperature Probe
- general purpose probe with stainless steel shaft
CAUTION:
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 Gage to acclimate and for the readings to stabilize when
moving the Gage between different environments.
When using the surface temperature probe, do not use excessive downward
force, and do not drag it sideways. When the Gage is not in use, place the
plastic cap over the surface temperature sensor to prevent damage.
NOTE:
For DPM-A Probes, do not touch or attempt to clean the hot wire
anemometer as damage to the sensor can result.
PosiTector bodies accept all PosiTector DPM, 6000, 200, SPG,
RTR, SST, SHD and UTG probes
