Troubleshooting
Most
PosiTector DPM L
conditions can be corrected by installing
a fresh CR2032 coin cell battery. If not, visit our Service & Support
page for information on sending your gage to us for a no charge
evaluation. See: www.defelsko.com/service
The PosiTector DPM L Probe does not appear in the PosiTector
App or in the PosiTector Advanced Gage Body after the battery
is inserted.
Check the battery in the probe and replace if required.
Ensure that the power switch inside the cap of the
PosiTector DPM
L
is in the ‘ON’ position. Ensure Bluetooth is enabled on the Smart
device running the
PosiTector App
or Bluetooth Smart within the
PosiTector
body.
NOTE:
Only probes within 10 m (30 ft) will be visible.
When the surface temperature probe is not on a surface, Air
Temperature (Ta) and Surface Temperature (Ts) appear to be
different.
Under normal conditions with the surface probe in air, Ta
and Ts should be within the combined tolerance of each sensor
(typically 1°C/2° F). It is possible for the difference to be larger if the
surface probe has recently been in contact with surfaces that are
at different temperatures than air.
RH value is slow to stabilize.
If the probe is exposed to very low
humidity for an extended time period and then placed in a high
humidity environment, the displayed Relative Humidity (RH) may
appear to respond slowly. Allow the probe to stabilize for 30 minutes
for a change of RH greater than 50%. It may take longer if the probe
was left at low RH for several months. To increase response time,
wrap the sensor in a damp cloth overnight to recondition the RH
sensor.
Surface Temperature reads much higher than expected.
The
probe tip may be dirty or damaged. Use care if attempting to clean
dirt or overspray from the sensor. If Ts continues to read high, then
return the probe for service.
