Introduction
Introduction
PosiTector DPM Dew Point Meter probes continually measures
calculate and record climatic readings, quickly and accurately.
This instruction manual specifically covers use with PosiTector
SmartLink.
The PosiTector SmartLink and free mobile app allow you to wirelessly
connect a wide selection of PosiTector probes to your smart device.
Take full advantage of your device's keyboard, microphone, camera,
internet data connection, etc. to simplify and enhance your
measurement inspection process.
(PosiTector SmartLink with PosiTector DPM probe shown)
The PosiTector SmartLink measurement solution consists of a
PosiTector App, PosiTector SmartLink device and compatible
PosiTector probe. In addition to the PosiTector DPM, compatible
probes include the PosiTector SPG/RTR-H (surface profile) and 6000
(coating thickness) .

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. Application at incorrect temperatures can
cause defects including: blistering, pinholing, cratering, dry spray
& mud cracking. By measuring surface temperature it is possible
to avoid potential application problems if air or surface
temperatures become too hot or too cold for satisfactory film
formation. Surface and air temperatures directly affect the rate of
cure of the applied coating or lining system and are major factors
in the formation of surface moisture or dew. ASTM D3276
Standard Guide for Painting Inspectors (Metal Substrates) states
that the minimum air/surface temperature is usually 5°C (40°F).
Relative Humidity -
the amount of moisture in the air expressed as a percent of overall
volume. High relative humidity can retard the rate of solvent
evaporation. For this reason, the maximum relative humidity at
which coatings or linings can be applied and cured is generally set
at 85%. This can be set as an alarm in the Advanced model.
Dew Point Temperature -
the temperature at which moisture will begin to form on a surface.
The dew point temperature is a function of air temperature and the
relative humidity. (see ISO 8502-4 Annex A). It is the temperature
to which a volume of air must be cooled in order to reach
saturation. A number of major standards organizations call for
careful dew point control. Moisture on a freshly blasted steel
substrate will cause the steel to rust. If a thin, invisible film of
moisture is trapped between the applied coating and the substrate,
the system will likely fail prematurely. To ensure that dew point
problems do not exist, ISO 8502-4 and SSPC guidelines state that
the surface temperature must be a minimum of 3°C or 5°F above
the dew point during the 3 critical phases of coating preparation,
application and cure.

Calibration
Calibration is the controlled and documented process of
measuring traceable calibration standards and verifying that the
results are within the stated accuracy of the Gage. Calibrations are
typically performed by the Gage manufacturer or by a certified
calibration laboratory in a controlled environment using a
documented process.
The PosiTector DPM is shipped with a Certificate of Calibration
showing traceability to a national standard. For organizations with
re-certification requirements, the PosiTector DPM may be returned
at regular intervals for calibration.
DeFelsko recommends that our customers establish Gage
calibration intervals based upon their own experience and work
environment. Based on our product knowledge, data and customer
feedback, a one year calibration interval from either the date of
calibration, date of purchase, or date of receipt is a typical starting
point.
Written Calibration Procedures are available online at no charge.

Operation Overview
Operation Overview
The PosiTector SmartLink powers-up when the LED button is pressed.
To preserve battery life, the PosiTector SmartLink powers-down after
5 minutes of no activity. Alternatively, press and hold the LED button
until it turns red and shuts off (approximately 5 seconds).
All probe settings and calibration adjustments are retained within the
PosiTector SmartLink, stored measurement data is retained within the
smart device (cell phone, tablet).
Wirelessly connect the PosiTector DPM probe to the smart device1
using the PosiTector App.
Remove the protective rubber cap from the surface temperature2
sensor.

4
Measure
A typical screen consists of RH, Ta, Ts, Td, Ts-Td and Tw
readings. This group of readings is referred to as a dataset.
RH - The relative humidity sensor is located inside the vented area of
the probe housing. The sensor may require a longer period to stabilize
in the event of extreme humidity changes.
Ta - The air temperature sensor is located inside the vented area of the
probe housing. (Also known as Dry Bulb temperature)
Ts - A surface temperature thermocouple is located on the tip of the
probe (built-in probe model). It is spring loaded and designed to quickly
self-align on a surface. Press it against a surface and allow a few
seconds for the value to stabilze. Do not drag the sensor over the
surface, Wet the surface for a faster response. Cover with the included
protective plastic cap when not in use.
For surface temperature measurement on steel over an extended of
time, consider using a PosiTector Standard or Advanced model with
optional Magnetic Surface Temperature probe. Both models feature
Auto Log mode for monitoring climatic parameter over extended
periods of time. Learn more: www.defelsko.com/dpm/
Td -The dew point temperature is a function of air temperature and
relative humidity (see ISO 8502-4 Annex A). It is the temperature to
which a volume of air must be cooled in order to reach saturation.
Ts-Td - 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.

5
Tw - The wet bulb temperature is the temperature of adiabatic
saturation. This is the temperature indicated by a moistened
thermometer bulb exposed to air flow.
The wet bulb temperature is calculated from Ta and RH using an air
pressure of 1.0 atmospheres (1013 mbar). It approximates the
temperature indicated by a moistened thermometer bulb exposed to
airflow. Variations of Tw at other pressures could be greater than +1°C
(+2°F).
Acclimate - The PosiTector DPM sensors may require a period of
time before the above climatic readings stabilize. This is most
noticeable when the instrument is relocated from one extreme
environment to another (i.e. from a warm location to a cold
location). A period of up to 30 minutes should provide adequate
time for stabilization.
NOTE:
Smart Trend Indicators
Identify rising, falling or stable readings. The instrument compares
each measurement with recent values to provide the current
direction of change.
While the absence of an arrow does not necessarily signify
stability, it can be taken to mean that particular reading is
undergoing little or no change. Slow changes could therefore
occur without being noted by an indicator arrow.

PosiTector App
PosiTector App
The PosiTector App connects a PosiTector SmartLink to your iOS
device enabling you to use PosiTector 6000, DPM, SPG or RTR-H
probes on your device without the need for a conventional gage body.
Screen fonts, brightness and displayed language are inherited from
your smart device settings. Currently, the PosiTector App has language
support for English, Spanish, French, German, Chinese and Korean.
Screen orientation is fixed to portrait only, rotation to landscape is not
supported.
Stored datasets, images and notes are all stored in the PosiTector App
(on your smart device). The number of stored datasets is only limited
by the memory available on your smart device. If the application is
removed or a Menu Reset (pg 23) is performed, all stored datasets and
associated data is permanently erased.
Prior to uninstalling the PosiTector App or performing a Reset
(pg 23) it is recommended that you synchronize/copy measurement
data to PosiSoft.net (pg 26) or share the batch data (AirPrint or email
report). This ensures that the data is saved for future reference.

PosiTector DPM DPM Probes Probes
PosiTector DPM probes continually measure, calculate and record
climatic readings. Two probe models (Built-In and Separate) are
offered, as pictured below.
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
K-Type probes:
Hand-held Surface Temperature Probe -•
for spot checking hard-to-reach surfaces
Self-adhering Surface Temperature Probe -•
sticks to solid materials including aluminum, wood, concrete,
etc. Ideal for unattended monitoring.
Liquid Temperature Probe -•
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. Allow time for the instrument to acclimate (pg 5) and
for the readings to stabilize when moving the instrument between
different environments. When using the surface temperature probe, do
not use excessive downward force, and do not drag it sideways.
More probe information is available at www.defelsko.com/dpm
Protective Cap
PosiTector DPM probes ship with a protective rubber cap (on surface
temperature sensor). Remove this cap prior to use. Replace it when
the instrument is not in use to protect the probe.

Every PosiTector DPM probe is factory calibrated and includes a
Certificate of Calibration. This factory calibration information is
permanently stored within the probe and cannot be adjusted or
overwritten by the user.
Certification
PosiTector DPM probes include a Certificate of Calibration showing
traceability to a National Metrology Institution. For organizations with
re-certification requirements, instruments may be returned at regular
intervals for calibration. DeFelsko recommends that customers
establish calibration intervals based upon their own experience and
work environment. Based on our product knowledge, data and
customer feedback; a one year calibration interval from either the date
of calibration, date of purchase, or date of receipt is a typical starting
