Getting Started with the DG-1000
Power on
Turn on the DG-1000 by pressing and holding the power button for 3 seconds until the
green power indicator light turns on. The bootup process may take up to 40 seconds to
complete, and the gauge is ready to be used when the home screen appears (shown
below).
Navigating the home screen
The DG-1000 runs multiple apps which can be launched via the touch screen.
Gauge app
To take measurements, you will need to launch the Gauge App. The DG-1000 will then
directly display the readings on both channels, as shown on page 4 and 5.
Tubing assistant
If you are just getting started or want condence you set up your equipment correctly,
use the Tubing Assistant App. It asks a few questions and then provides step-by-step
instruction on getting the gauge and tubing set up correctly for the test being run.
Updates
The DG-1000 has a regular cadence of rmware updates which add features and
capabilities to the gauge. Anytime you are connected to Wi-Fi, you can use this to
update and ensure your gauge has the latest software loaded.
Settings
From the home screen, settings provides ability to establish multiple universal settings,
like: Bluetooth®, Wi-Fi, screen brightness, language, factory reset. Note that when in
the gauge app, the settings button allows you to establish gauge specic settings as
shown on the following pages.
Power off
In addition to the hard power button on the top, there is a power button on the home
screen.

Battery information
The DG-1000 uses two lithium-ion batteries that are rechargeable and replaceable. TEC
recommends using only protected batteries with a button on one end, as seen here:
TEC recommends the Tenergy Li-Ion model 30016
battery (size 18650, 2600mAh, 3.7v, protected).
Do not use unprotected batteries.
Battery run time and storage
Battery run time is 15 hours, depending on WiFi use and screen brightness. To help
preserve the battery run time, TEC recommends keeping the screen brightness at or
below 40% and to turn off WiFi when not needed. All batteries self-discharge over
time. TEC recommends charging the batteries for a few hours once every three months
using the fast charger regardless of battery level. Batteries should be charged in
temperatures between 32 degrees F and 105 degrees F.
Charging instructions
On DG-1000 units with serial numbers 9541 and above, the batteries can be fully charged
in about three hours using the included USB Type C charger. When connected to power
the green indicator light will illuminate. The amber indicator light will illuminate during
charging and will turn off when fully charged. The amber indicator light will blink if
there is a charging error. The gauge may be used during charging.
On DG-1000 units with serial numbers 9540 or lower, the batteries can be fully charged
in about three hours using the fast charging port and included barrel jack charger.
TEC recommends using the included power supply for optimal charging.
Calibration information
The DG-1000 should be calibrated at the TEC calibration lab once every four years.
A calibration label is located on the back of the gauge that includes the gauge serial
number and the date it was last calibrated. This information is also available in the
DG-1000 settings screen (see the Basic Use Quick Guide to learn more).

Temperature thresholds
The DG-1000 should be stored in a dry place with temperatures between -4 degrees F
and 140 degrees F. Operating temperatures are between 42 degrees F and 115 degrees F.
Recovery or requirement to return to factory settings
There is a very rare possibility that the DG-1000 may become locked or completely
unresponsive to the touchscreen. Press and hold the power button for 5 seconds to
turn off the DG-1000. Wait until all lights are off. Then press the power button. This
typically resolves many issues. If that fails to work, press and hold the power button for
5 seconds to turn off the DG-1000. When completely off, turn the DG-1000 over, unscrew
the battery cover, remove batteries, return them into gauge, screw the battery cover
back on, press the power button.
If the DG-1000 fails to recover after trying both actions, consult with TEC technical
support rst by calling 612-827-1117.
Bluetooth®communication
The DG-1000 is equipped with Bluetooth® communication and is an ideal way to connect
to TEC apps installed on your Android or iOS device. Connection over Bluetooth® allows
both your mobile device and the gauge to remain connected to a Wi-Fi network during your
testing and enables the DG-1000 to be used with the Digital TrueFlow® and TrueFlow®HVAC
app for testing HVAC system air ow.
WiFi Communication and Password
The password for the networking setting WiFi (Create Network) is dg1000pw. To learn more
about the DG-1000 networking settings, see the Ports and Networking Basics Quick Guide.
USB Communication
The DG-1000 can be connected to a computer through the USB Type C port (or micro-USB
port on guages with serial number 9540 or earlier) . Cables rated for USB 2.0 or above can
be used with the gauge.
The USB Type A port is intended for use with accessories such as a keyboard and is not
designed for digital communication to a computer.

Safety, warnings and troubleshooting information
• Follow all safety instructions provided when used with any TEC products.
• Do not operate the gauge if any liquid gets inside the gauge.
• If the inside of the gauge gets wet, immediately turn off the gauge and remove the
batteries.
• Leave the battery compartment cover off to allow for drying.
• Dry the batteries with a towel and allow the batteries to air dry for at least 12 hours.
• Allow the gauge to air dry for at least 12 hours before inserting the batteries and
powering back on.
• If a liquid gets inside the pressure ports, contact TEC at 612-827-1117.
• Do not attempt to dry any of the electrical connectors with a Q-Tip or similar item.
Lithium Ion battery safety and warnings
• Do not leave the batteries in direct sunlight or in an area heated by sunlight. The
