The PosiTector DPM powers-up when the center navigation
button is pressed. Readings are updated automatically each
second. To preserve battery life, the instrument powers down after
approximately 5 minutes of no activity. All settings are retained.
1. Remove the protective rubber cap from the surface
temperature sensor.
2. Power-up Gage by pressing the center navigation button.
A typical instrument screen is shown below, consisting of RH, Ta,
Ts, Td, and Ts-Td readings. This group of readings is referred to as
a dataset.

Alarm Mode
Alarm Mode
Alarm
The PosiTector DPM can automatically alert the user when
current climatic conditions exceed pre-set values. When selected,
the Alarm icon is displayed at the the top of the screen.
Standard models 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.
Advanced models allow the user to set up custom alarm
conditions for each reading in a dataset.
Setup Menu
Setup Menu
Reset
Reset (soft reset) restores factory settings and returns the
instrument to a known condition. The following occurs:
- All batches and stored datasets are erased.
- Menu settings are returned to the following:
Memory = OFF
Auto Log = OFF
Perform a more thorough Hard Reset by powering down the
instrument, waiting several seconds, then simultaneously holding
both the center and (+) buttons until the Reset symbol
appears. This returns the instrument to a known, “out-of-the-box”
condition. It performs the same function as a menu Reset with the
addition of:
- Bluetooth Pairing info is cleared.
- Alarm settings are set to defaults.
- Menu settings are returned to the following:
Units = Celsius
Flip Display = Normal
Auto Sync = OFF
Alarms = OFF
Alarm Sound = OFF
Wet Bulb = OFF
White on Black = OFF
NOTE:
Date, Time and WiFi are not affected by either Reset.
Bluetooth = OFF
Trend Chart = None
Language = English
Battery Type = Alkaline
Backlight = Normal
Auto Log Interval = 5 min
Bluetooth Streaming = OFF
USB Drive= ON

Advanced models only)
Wet Bulb
(
When selected, the wet bulb temperature (Tw) is displayed 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. Wet Bulb readings cannot be stored in memory.
Trend Chart
(Advanced models only)
Displays a real-time graph of the readings over
the last three minutes. Use Trend Charts to
monitor short-term environmental changes and
spot trends.
Shortcut:
Press the Up button to scroll through
the trend charts.
NOTE:
Trend charts can only be displayed when memory is off.
Battery Type
Selects the type of batteries used in the Gage from a choice of
“Alkaline”, “Lithium” or “NiMH” (Nickel-metal hydride
rechargeable). If NiMH is selected, the gage will trickle charge the
batteries while connected via USB to a PC or optional AC charger.
The battery state indicator icon is calibrated for the selected
battery type. No damage will occur if the wrong battery type is
selected.
NOTE:
DeFelsko recommends the use of eneloop (NiMH)
rechargeable batteries.

Memory Management
Memory Management
The PosiTector DPM has internal memory storage for recording
measurement datasets. Stored datasets can be reviewed
on-screen or accessed via computers, tablets and smart phones.
Datasets are date and time-stamped. Datasets can be stored
manually (using the (+) button), or automatically using the Auto
Log mode (Page 5).
Standard models store up to 2,500 datasets in one batch.
Advanced models store 20,000 datasets in up to 1,000 batches.
“New Batch” closes any open batch and creates a new batch name
using the lowest available number. The icon appears. New
batch names are date stamped when they are created.

in memory and can be accessed when connected to a computer
(see PosiSoft USB Drive pg. 6).
Auto Log Mode
Auto Log Mode
The PosiTector DPM can automatically display and record
datasets at user selected time intervals. When selected, the Auto
Log icon will appear on the display, with a countdown timer

NOTES:
-Auto Log continues recording until memory is full, the instrument
loses power, or the user turns off Auto Log mode. Stored datasets
will remain in memory.
-To conserve battery life, readings update only at the Log Interval.
The last recorded readings will remain “frozen” on the display until
the next dataset has been stored.
-It is recommended that fresh alkaline batteries be installed prior
to an extended Auto Log.
PosiSoft solutions for viewing, analyzing and reporting data:
PosiSoft USB Drive - connect the PosiTector to a PC/Mac using
the supplied USB cable to access and print stored readings, graphs,
photos, notes and screen captures. No software or internet
connection required. USB Drive (pg. 7) must be selected.
PosiSoft.net - a free web-based application offering secure
centralized storage of PosiTector readings. Access your data from
any web connected device. Go to: www.PosiSoft.net
PosiSoft Software - Desktop Software for downloading, viewing
and printing your measurement data.
PosiSoft Mobile (Advanced models only) - access readings, graphs,
capture photos and update annotations through WiFi enabled
devices, such as tablets, smart phones and computers.

Sync Now
When selected, Gage immediately synchronizes stored
measurement data via USB, Bluetooth or WiFi to PosiSoft.net.
(PosiSoft Desktop Manager and an internet connection are
required when using USB or Bluetooth.)
Auto SYNC
Allows the Gage to automatically synchronize with PosiSoft.net
when initially connected to the internet via a PC running PosiSoft
Desktop Manager or a local WiFi network.
Additional measurements added to memory while connected are
synchronized only when the USB cable is disconnected, then
reconnected or when the Sync Now option is selected.
USB Drive
The Gage uses a USB mass storage device class which provides
a simple interface to retrieve data in a manner similar to USB flash
drives, cameras or digital audio players.
NOTE:
When connected, power is supplied through the USB
cable. The batteries are not used and the body will not
automatically power down. If rechargeable (NiMH) batteries are
installed, the Gage will trickle charge the batteries.
Bluetooth
Allows individual readings to be sent to a computer, printer or
compatible device as they are taken using Bluetooth wireless
technology. See www.defelsko.com/bluetooth
WiFi
Allows wireless communication with devices such as tablets,
smart phones and computers connected to your local wireless
network or portable mobile hot spot. See www.defelsko.com/WiFi

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 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. When the instrument
is not in use, place the rubber cap over the surface temperature
sensor to prevent damage.

Returning for Service
Returning for Service
Before returning the instrument for service…
1.Install new batteries in the proper alignment as shown within
battery compartment.
2.Examine the surface temperature sensor for dirt or damage.
3.Perform a Hard Reset. (see pg. 3)
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.
