    - Certificate of Calibration traceable to NIST - Two (2) year warranty on Body and Probe Quick Start Quick Start The PosiTector DPM powers-up when the center navigation button is pressed. Readings are updated automatically each second. To preserve battery life, the Gage powers down after approximately 5 minutes of no activity.

  • Page 6: Operation Overview

    Protective Cap The PosiTector DPM is shipped with a protective plastic cap over the surface temperature sensor. Remove this cap prior to use. Replace it when the Gage is not in use to protect the sensor. Wrist Strap We recommend attaching and wearing the supplied wrist strap.
  • Page 7 d - The surface minus dew point temperature is important in judging the risk of condensation, or dew, forming on a surface. For example, ISO 8502-4 recommends that, unless otherwise agreed, the temperature of a steel surface generally should be at least 3°C (5°F) above the dew point when paints are applied.

  • Page 9: Why Is Measurement Important

    Why is Measurement Important? Why is Measurement Important? For industrial painters, the primary reason for measuring climatic conditions is to avoid rework and the premature failure of protective coatings. Recommendations and requirements are covered under various internationally recognized standards. Temperature – It is important to measure both surface and air temperatures as they are often different.

    Probes Probes Separate probe with magnetic Surface surface temperature temperature sensor sensor Air temperature and humidity sensors Optionally, the Magnetic Surface Temperature Probe can be disconnected from the K-Type thermocouple connector (separate probe models only) and replaced with one of the following accessories: Hand-held Surface Temperature Probe - for spot checking hard-to-reach surfaces...
  • Page 11 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.

  • Page 12: Menu Operation

    Menu Operation Gage functions are menu controlled. To access the Menu, power-up the Gage, then press the center navigation button. Below is a sample menu for a PosiTector DPM Advanced Model: Memory Auto Log Some buttons have a tick box to their right to indicate current status.

  • Page 13: Alarm Mode

    Alarm Mode Alarm Mode The PosiTector DPM can automatically alert the user when cur- rent climatic conditions exceed pre-set values. When selected, the Alarm icon is displayed at the top of the screen. According to ISO 8502-4 and ASTM D3276, steel surfaces should generally be 3°C (5°F) above the dew point when painting.

  • Page 15: Wet Bulb Temperature

    Wet Bulb (Advanced models only) Displays the wet bulb temperature (Tw) on the main screen. It is calculated from Ta and RH using an air pressure of 1.0 atmospheres (1013 mbar). Variations of Tw at other pressures could be greater than ±1°C (±2°F). NOTE: This menu item only appears when all memory functions are turned off.
