1. Why is the software not detecting my gauge when I click “Find Gauges”? (USB Device is not recognized)

    Why is the software not detecting my DM-2 or DM32 gauge when I click "Find Gauges"? 

    When I plug the gauge in to the USB port, MS Windows says USB device is not recognized with the following possible errors:

    1. Code 43 Error
    2. USB Device is not recognized

    (If "Access denied" or "Error 5" is displayed in the error message in FanTestic, you have a different problem)

    I have already tried the following:

    • uninstalled and reinstalled the correct 32/64 bit DM-2 or DM32 USB driver
    • uninstalled and reinstalled FanTestic software

    It's a possibility the USB port on your computer is not providing enough power for it to detect the DM-2 or DM32 gauge.  This is possible on laptops or tablets [confirmed issue on the MS Surface Pro Tablet running Windows 8.1].&nb

  2. Can I control my DM32 over Ethernet and still plug the DM32 USB into a computer for power?

    In order to do both, you need to be sure you have version 5.8.30 of FanTestic or later. 

    In all versions of FanTestic before version 5.8.30,  if you plugged a DM32 into a computer USB to give it power (instead of plugging into the wall adapter) FanTestic would assume you also wanted to use USB Serial connection for control.  FanTestic made this assumption even if the gauge was also connected to the computer over Ethernet (via the Network cable or via WiFi). 

    In all versions starting with 5.8.30, FanTestic discovers gauges connected via Ethernet first, so it can ignore the same gauge also found on USB Serial. 

    This change allows users to have their DM32 connected for control via Ethernet but also connect the DM32 to the computer USB port for power (if it is more convenient than connecting to a wall outlet).  Retrotec recommends that users use Ethernet connection rather than USB for controlling th

  3. How do I get the latest version of FanTestic?

    Updates of FanTestic are released regularly.  How do I know if I have the latest version, and how do I get it?

    Users who are using the ADMIN shortcut with FanTestic or who have skipped an update will not necessarily be notified of the update when they start the software. 

    To install the new FanTestic:

    If you have a current version of  FanTestic, open it while connected to the internet, use the File menu>>Check for Updates  and then restart if it tells you that there is a new version available. (old versions of FanTestic do not have this option in the File menu, and some old versions have it but it can crash on some computers).

    If you have trouble installing the update using the "Check for Updates", uninstall FanTestic using the control panel and re-install from the following link:

  4. How do I install FanTestic or Integrity using Chrome, Firefox, or MS Edge browsers?

    If you are using a browser that is NOT Microsoft Internet Explorer you may get errors when you run the setup.exe that you downloaded.  If you get errors, use Microsoft Internet Explorer and choose to "Run" the installer from the internet rather than downloading.

     The FanTestic and Integrity installer relies on the use of the Internet Explorer Browser, as do all applications distributed using ClickOnce technology.  In order to successfully install, start Internet Explorer on your computer and navigate to the download link in Internet Explorer.  If your computer has a different browser set as default, you will have to copy the link from that browser into Internet Explorer.

    On Windows 10, the new Microsoft Edge browser is NOT Internet Explorer.  On Windows 10, you must type "Internet Explorer" into the Cortana search bar and choose to open "Internet Explorer (desktop)".

    If you continue to have errors installing when using Inter

  5. My duct test using DW/143 is not compliant, what am I doing wrong?

    I am doing duct testing and use the DW/143 standard (UK).  FanTestic keeps telling me the test is not compliant, what am I doing wrong?

    FanTestic checks that you have held the ducts at the test pressure for at least 900 seconds.  If you do not, the test will show as not compliant.  If you did a manual test and are entering the information into FanTestic, be sure to enter the time over which the test pressure was held.  If this is greater than 900 and your other test conditions are correct, the test will show compliant. 

    Compliance means the test conditions comply with the stated requirements for a test  in DW/143.  Pass or fail means that the measured results are within the required level.

  6. How do I pass a small room?

    I am having diffuculties passing a small room with an integrity test.  Is there anything I can do or allowances I can make?

    1. Make sure all the sealing has been completed.
      1. Most often small rooms leak at the wall to lower slab joint. This must have a continuous caulk bead from the sheetrock to the concrete slab.
      2. Next, check the wall to ceiling slab joint. It must be continuous and can usually be sealed with expanding foam. Paint over with intumescent paint if a fire rating is a concern.
      3. Next, all cable bundles must be checked for leaks through the center of the bundles. Separate the cables and sealed between each cable.
      4. All ducts entering or leaving the space must be dampered but even when seating properly those dampers alone may be enough to make the room fail. A smoke tight damper must be used.
    2. If a suspended ceiling is in place.
      1. Consider flooding the space above the suspended

  7. How do I get the factory default report template for FanTestic?

    FanTestic provides a report template that users with Pro licenses can customise.  If users have done customizations and not given the template a name different than the default template, they will not always be able to see the new factory template after a FanTestic update.

    FanTestic provides a report template that users with Pro licenses can customise.   This template can then be used when the user generates a report from their test data. 

    One  way to get a copy of the current factory default template is to use the menu item in the File menu called "Customize Report Template".  This will create a copy of the factory default template in the MyDocuments\Retrotec\Templates directory with the name of the factory default template plus "_To_Customize-[yyyy-MM-dd]".

    The default Template is named with the name of the standard you are using, and the language.   So if you are using ASTM standard with t

  8. Why is the positive peak pressure for FM200 zero or negative?

    How can the positive peak pressure be calculated as a negative number or zero when there is a value provided for the leakage area required for venting?

    The calculation of peak pressures depends on a curve, and when the circumstances are particular, the peak pressures can be very close to zero.  The curve is not optimized in this area, as peak pressures near zero are not a worry.  Integrity makes the value of peak pressure zero when the calculated value using the curve goes below zero, as at this point it does not matter how small the pressure really is.

    Previous versions of the software variously showed the positive peak pressure as negative or as a blank instead of a zero. 

    - blanks instead of zeros in report are fixed in Integrity versions >
    - peak pressures showing negative instead of zero in the UI fixed in Integrity versions >

  9. How can I get rid of the warning about envelope area in FanTestic Integrity?

    When calculating hold time using FanTestic Integrity software, I am getting an error which says "Envelope area not specified. Unable to determine permeability result." but there is no place to enter envelope area.  How can I get rid of this warning?

    If you are seeing the following error:

    you can prevent it from coming up by modifying your settings.xml file.

    You can find your settings.xml file in your MyDocuments/Retrotec/AppData directory.  Open it using Notepad (you can right-click on the filename and choose "Open with" and then click on "Notepad").

    If you are using one of the NFPA standards, add the following text to the file:  <Setting Name="NFPAPermeabilityRefPa">0</Setting>

    When you are done it should look like:

  10. Can I install FanTestic on a Windows 8 computer?

    FanTestic will install properly on a Windows 8 computer, as long as it is full Windows 8 and not one of the tablet or phone versions of Windows 8. 

    Make sure to disable anti-virus while doing the download and install. 

    Be sure to “Run” the installer from the internet using Internet Explorer browser, do not download it to the computer and then run it.

    If you have trouble installing FanTestic, you can first install the DM32 USB Driver directly from the website (the version on the website has an up to date certificate) and then run the FanTestic installer. 

    (Older versions of the FanTestic installer had a DM32 USB Driver which did not have an up to date security certificate so some settings on Windows 8 could cause it to reject the installation. )
