TEC DG-8 Pressure Gauge User Manual

OVERVIEW

Product Overview

Where to use the TEC DG-8

Who is the target audience for the DG-8?
The DG-8 provides highly accurate single-channel pressure measurements and is designed to support professionals who use manometers and micro-manometers today. This includes weatherization professionals, energy raters, home performance contractors, HVAC technicians, radon mitigation professionals, hospital building facilities personnel and others.

Why did TEC create the DG-8?
TEC set out to create an easy-to-use single channel pressure gauge in a compact package with the same focus on accuracy and reliability found in the entire line of diagnostic products. The DG-8 is a convenient and cost- effective choice for making key building pressure measurements, including room pressures as a part of air balancing, zonal pressure diagnostics, CAZ depressurization and draft testing, radon sub-slab, external static pressure and many more. The competitive price point of the DG-8 makes TEC accuracy more accessible than ever before.

Using Instructions

What are some key features of the DG-8?
The DG-8 is simple to use and provides accurate readings even at very low pressures. The large readout on a backlit color display, durable case and Bluetooth® communication make the DG-8 a highly versatile tool for a variety of applications.

Which TEC apps and products are compatible with the DG-8?
The DG-8 can be used with the TEC Gauge app (Android and iOS) to quickly monitor and record your pressure measurements. It can also be used with the TEC Exhaust Fan Flow Meter and both sizes of the TEC Pressure Pan.

Powering on and off the DG-8

To power on the DG-8 press and hold the power button for 3 seconds until button flashes green. To power off the DG-8 press and hold the power button for 3 seconds until button flashes red.

Battery information

The DG-8 uses a single protected lithium-ion polymer battery that is rechargeable, but is not user-replaceable.

Battery run time is typically 22 hours. All batteries self-discharge over time; TEC recommends charging the battery using the included fast charger at least once every three months regardless of battery level.

Charging instructions

The DG-8 battery is charged through its USB-C receptacle. When using the included USB-C power supply and USB-C cable, the DG-8 will charge from empty to 100% in approximately 2 hours. When charging the DG-8 using an aftermarket USB-A to USB-C cable it will take approximately 5 hours to fully charge from empty.

When the DG-8 is connected to a power source, the green LED light next to the USB-C port will be lit. While the battery is actively charging the orange LED light located on the opposite side of the USB-C port will be lit as well. Once fully charged, the orange LED will turn off.

The DG-8 battery should only be charged between 32° F and 115° F (0° C and 45° C).

TEC recommends using the supplied USB-C cable and power supply for optimal charging.

Temperature thresholds

The DG-8 should be stored in a dry place with temperatrue between 32° F and 77° F (0° C and 25° C). Operating temperatures are between 32° F and 115° F (0° C and 45° C).

Calibration information

The DG-8 should be calibrated at the TEC calibration lab once every two years. The date of calibration can be found on the label on the back of the gauge. Visit the TEC website for more information on arranging calibration service.
