USB Driver for DG-500 & 700

Newer DG-700 and DG-500 gauges contain both a USB (located on the left in the picture) and a DB-9 Serial Communication Port (located in the center of the picture), either of which can be used to create a 2-way communication link between the gauge and a computer. This communication link can be used (along with TEC software) to conduct automated Blower Door tests and to data log both pressure channels.

-   Fully automated Blower Door testing requires a DG-700 gauge, TECTITE software, a Blower Door fan speed controller with a communication jack (standard equipment since September 2004), a fan control cable, and a communication cable (either USB or 9 pin serial) to connect the DG-700 to a user supplied laptop computer. (If using a TEC WiFi Link, no communication cable is necessary.)

-   Data logging of pressure measurements requires the TECLOG software, and a communication cable (either USB or 9 pin serial) to connect the DG-700 or DG-500 to a user supplied laptop computer.

In order for the Digital Gauge to communicate with your computer using a USB port, drivers must be installed.  You will know if the drivers have not been installed when you plug in the Digital Gauge into your computer, run TECTITE and you see a message that says that the Gauge is not communcating with TECTITE.  The driver file needs to be installed anytime you change computers.

  • Estimated design infiltration rates can be used in Manual J load calculations.
  • Choice of report formats including a simple easy-to-read homeowner report, or a detailed technical report.
  • Compare feature generates test result comparison report for any two previously saved building files.


TECTITE Express 4.0 (WiFi) Unique Features

  • Choice of 3 airtightness test standards: ASTM E779-10, CGSB 149.10-M86 and EN 13829.
  • Can combine both pressurization and depressurization tests in the same test file.

Mobile Apps (iOS and Android)

iTEC-700

The free iTEC-700 App is a utility that provides wireless display and control of your DG-700 pressure gauge using your Apple or Android device and a TEC WiFi Link.  The iTEC-700 App has more calculations and building metrics all in the convenience of phone or tablet.  iTEC-700 also has flow calculations for the new Ring 4 for the Duct Blaster® fan.

The convenience of the iTEC-700 App allows you to remotely turn on, turn off or adjust a Minneapolis Blower Door fan or a Duct Blaster fan.  Useful when you are doing Blower Door guided air sealing.  Another application is to leave your Digital Pressure Gauge in the combustion appliance zone (CAZ) and then walk around the house turning on exhaust fans and determining the extent of depressurization that occurs to the vent and the CAZ while looking at your phone or tablet.

iTEC-RESNET

The free iTEC RESNET App makes it easy to comply with the data collection and reporting requirements of the new RESNET One Point Airtightness Test, as specified in Chapter 8 of the RESNET Performance Testing Standards. iTEC RESNET allows the user to manually enter the required Blower Door airtightness data, calculate test results, record customer and building information, display test results and email an HTML report. In addition, project files can be geotagged, time stamped and a single photograph from the camera roll can be linked to the project file. Finally, the application can email a project test file that is compatible with our new TECTITE 4.0 (WiFi) Blower Door PC software.

ZPD Calculation Utility (PC)

The Zone Pressure Diagnostics (ZPD) Calculation Utility provides a way to estimate the leakage from one zone to another.  It can help to prioritize air sealing activities.  The ZPD Calculation Utility uses Minneapolis Blower Door™ tests taken with the house closed with zone pressure taps to the garage, the attic or the crawlspace.  An opening is then made to the suspected zone, such as opening a door, and then running the Blower Door test again and noting changes in the zone pressures.
