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.
Surface temperature value does not agree with expected surface temperature or surface temperature probe is slow to respond.
In some cases, the surface being measured is very rough and a good thermal connection from the probe tip to the surface is not possible. If possible place a small drop of water on the surface and then place the probe tip into the water drop. Quick and accurate results can be obtained in this manner.
Returning for Service
For issues related to the PosiTector DPM L probes:
- Install new batteries in the proper alignment with positive side up.
- Examine the sensor for debris or damage.
- Re-attempt measurement.
For issues related to the PosiTector Advanced Gage Body:
- Perform a Hard Reset* as follows:
A) Power down the Gage and wait 5 seconds.
B) Simultaneously press and hold the (+) and center buttons until the Reset symbol appears.
- Update your PosiTector gage body and re-attempt measurements.
*WARNING: This returns the Gage to a known, "out-of-box" condition. All readings in memory will be erased.
If these steps do not resolve the issue, visit our Service and Support page for information on sending your Gage to us for a no charge evaluation. See www.defelsko.com/service
