Parts of the DG-1000

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 confidence 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 firmware 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 specific 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.

Gauge app screen overview
To learn more about how to use the Gauge app, download the DG-1000 Basic Use Quick Guide at energyconservatory.com/dg1000guides.

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 first 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 flow.

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.
