Any Windows laptop or desktop PC, or full Windows tablet. USB driver support to connect the DG-500, 700 or 1000 must be installed and is available in a Windows Driver update. The driver is also available from the Software Page.

When using TECTITE, a pop up message comes up saying:  WARNING! Excessive building pressure fluctuation for current target pressure. What causes this and what are my options?

While attempting to reach a target pressure line, the measured building pressure has been fluctuating beyond the Target Tolerance for more than 90 seconds. In order for TECTITE to start taking data at any target pressure line, it must first determine that the current measured building pressure is within a specified range from the target building pressure.  This specified range is called the Target Tolerance. If the current measured building pressure is fluctuating beyond the Target Tolerance, then data collection for that target pressure will not begin. 

Fluctuating building pressure readings are often caused by improper installation of the building pressure reference tubing, or by windy weather. To determine the cause of the problem: 

• First check to be sure that the outside end of the building pressure tubing (e.g. the green tubing connected to the Channel A/P1 Reference tap) is not placed directly in the exhaust air flow of the Blower Door fan. You must be careful to run the end of the tubing well away (at least 5 feet to the side) from the exhaust of the fan.  A good location for the end of the building pressure tubing is at the base of the building where it meets the ground. 
• If the building pressure tubing is installed correctly, the fluctuating building pressures are possilby caused by wind. Try increasing your Target Tolerance to 3 or 4 from the default value of 2 (the Target Tolerance can be changed by clicking on the ADJUST AUTO TEST SETTINGS button in the warning screen). If this doesn’t work, increase the Target Tolerance to 5 or greater. 

Note: As the Target Tolerance is increased from the default value of 2, gathered data may not be as close to the target pressure lines as would be the case when using the default value. This has negligible effect on the final test results. However, some test standards do require that the measured building pressures be within a specified range of the target pressure (e.g. the CGSB test standard requires that the measured building pressures be within +/- 2.5 Pa of the specified target pressure).

• In windy conditions, you may wish to use the SAMPLE button on the Test Graph to force a reading to be taken despite the fluctuating building pressure. Whenever the computer is seeking a target building pressure, clicking on the SAMPLE button causes the computer to proceed as if it had decided that the Target Tolerance has been met.
• Check the version of TECTITE that is installed on your computer by clicking on the Help pull down menu and choose About TECTITE. Version 4.0.38.0 has a known issue that will cause this error to occur when you have higher baseline readings. Uninstall this version and install the latest version from our website.

We have the following recommendations to try if you encounter a problem in the future.

(Try these in the order listed below):

1. Try to quit the apps that are an issue. To do this by pressing the home button twice to see the bar of apps on the bottom of the screen. Find the apps that are not responding and long press onto the app until it shakes. When it starts to shake, touch the red negative sign in the corner of the app. This will not delete, but will close the app. Then open and retry to see if it works.

2. If not, than restart the ipad. Press the power switch until you get the slide lock to power off. Turn back on and retry.

3. If not, than reset the ipad. Press the power switch and the home button until the screen turns off. May take a few seconds to power off.

TECLOG3 will gather more data and allow you to see a real-time graph. TECTITE is more automated and generates a more comprehensive report for testing homes.

Windows 10 introduced a feature that allows a user to scroll inactive windows when the mouse is hovering over them. It appears that the chart control in TECLOG3 does not respond properly to this feature if it is active, as the scroll event is trying to move the contents of the window. To disable the feature, go to Start Menu, Settings, Mouse & Keypad and turn off the “Scroll inactive windows when I hover over them” option. We will investigate further if we can override this behavior from within TECLOG3. We have also added this to our list of issues for future releases of TECLOG.

No. The reports will always show the date of the last time it was calibrated at TEC. To provide information about the frequent calibration checks of your gauge, you should include a copy of your calibration log with your TECTITE report.

With some earlier versions of TECTITE 4.0 you can not save a file without actual test results. Even though you entered the house info, there is no baseline, flow at 50, etc. The best way to do what you want is to create a Configuration file. With all of the house info entered go to File then Save Configuration File. Save it with a name that makes sense to you. Then instead of Retrieving a Test File, you want to go to File then New Test with Custom Configuration. You can also download the latest version of TECTITE 4.0 which has corrected this issue.

No. The Energy Conservatory provides all of its software free of charge including TECTITE, TECTITE Express, TECBLAST, and TECLOG2. You can download any of our software products at any time. Some software downloads have a 30 day trial period. They are fully functioning software. Call The Energy Conservatory at 612-827-1117 and ask about making your software work for more than 30 days.

You can only connect to one WiFi network at a time. If you want to connect to multiple DG-700s you need to put the WiFi Links into router mode and connect all gauges to the router and then connect the router to your computer.
