Troubleshooting

Before returning for service...
  1. Install new batteries in the proper alignment as shown within battery compartment.
  2. Examine the sensor for debris or damage.
  3. Perform a Hard Reset.
  4. If issue is not resolved, Update your PosiTector gage body and re-attempt measurements.

IMPORTANT: If you must return the Gage for service, describe the problem fully and include measurement results, if any. Be sure to also include the probe, your company name, company contact, telephone number and fax number or email address. See the Service & Support page for more information.

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:

  1. Install new batteries in the proper alignment with positive side up.
  2. Examine the sensor for debris or damage.
  3. Re-attempt measurement.

For issues related to the PosiTector Advanced Gage Body:

  1. 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.
  2. 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.

PosiTest HHD will not detect holidays...

  • Check Electrode Connections: With the detector powered OFF, check all connections. Ensure the extension rod is fully engaged with the barrel of the PosiTest HHD and the lock gate is engaged.
  • Check Ground Connections: With the detector powered OFF, remove the ground cable and fully reinsert it twisting clockwise 180° until locked. Ensure the opposite end is clean and well connected to the substrate of the coating system being inspected.
  • Check Test Voltage: If the test voltage is too low, the PosiTest HHD will not find holidays.
  • Reduce Travel Speed: Recommended travel speed of the PosiTest HHD is a maximum of 0.3m/second (1ft/second). Since the PosiTest HHD operates at a pulse repetition rate of 30 pulses per second, it is possible to miss holidays if the travel speed exceeds the recommended maximum.

PosiTest HHD turns OFF while in use...

  • Check Battery: A low or defective battery will not be able to sustain the power required to operate the PosiTest HHD. Charge or replace the battery. To determine if the battery is defective refer to Battery Charging (pg. 12 of manual).

When generating high voltage, the PosiTest HHD display is lower than the test voltage...

  • The PosiTest HHD integrated jeep/crest meter ALWAYS displays the actual voltage being generated. Although the PosiTest HHD will regulate the output voltage to match the test voltage, there are circumstances when it is not possible to generate the test voltage. For example, overloading of the electrode by setting the voltage higher than recommended for the coating system under inspection may result in a generated voltage lower than the test voltage. Reducing the brush or electrode size will also reduce loading.

IMPORTANT: If you must return the Detector for service, please fill out and include the Service Form located on our Service and Support page with the Detector. Be sure to also include the probe, your company name, company contact, telephone number and fax number or email address.

NOTE: When returning the PosiTest HHD for service or repair, DO NOT include any batteries.

There are no user serviceable components. Any service must be performed by DeFelsko Corporation.

IMPORTANT: If you must return the Gage for service, describe the problem fully and include measurement results, if any. Be sure to also include the probe, your company name, company contact, telephone number and fax number or email address. See the Service & Support page for more information.
