Page 4: Introduction
Introduction Introduction 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. All settings are retained. - Page 5 DPM-D probes only display RH, Ta, & Td NOTE: 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.

Page 6: Operation Overview
Operation Overview Operation Overview 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 button activity. All settings are retained. - Page 7 For surface temperature measurement on steel over an extended of time, consider using the optional Magnetic Surface Temperature probe (pg. 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 protective coatings are...

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. -
Page 10: Probes
The PosiTector body accepts a wide variety of probe types including magnetic, eddy current and ultrasonic coating thickness, surface profile, shore hardness durometer, salt contamination and ultrasonic wall thickness probes. See www.defelsko.com/probes PosiTector DPM probes: PosiTector DPM PosiTector DPM-S Integral Surface Temperature Sensor Magnetic Surface Temperature Sensor Surface Temperature Air Temperature &... - Page 11 - 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.

Page 12: 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: Some buttons have a tick box to their right to indicate current status. An empty box indicates that feature is not active. - Page 13 Standard models have one, fixed alarm. When selected, the Gage will alert the user when the surface temperature is less than 3°C (5°F) above the dew point temperature. Enable by selecting the tick box. The Gage will alert the user with an audio tone and the LCD screen will reverse (see right) when conditions may be unsuitable for painting.
