  • Page 13: Additional Information On The Break-Out Box

    4.1 Additional Information on the Break-Out Box When your HFM1 arrives from ICT International you do not have to change any of the break-out box settings, having already been configured for HFP01 and THERM- MICRO sensors. The Break-Out box should have the Power Selector Switch always set to Internal Battery.

  • Page 14: Install The Hfm1 Software & Usb Driver

    Install the HFM1 Software & USB Driver Insert the supplied USB drive and run Autorun.exe. Choose Software (a) then choose ICT Instrument Software (b). Follow the on-screen prompts until the finished installation screen appears. To install the USB driver, choose USB Driver (c) and wait for the installation to complete.

  • Page 15: Turn The Hfm1 On

    Turn the HFM1 On To charge and turn on your HFM1, connect the Instrument to a computer via a USB cable. Alternatively, the HFM1 can either be turned on manually by pressing the power button or automatically by connecting an external power supply.

  • Page 16: Connecting To The Hfm1

    Connecting to the HFM1 Connect the USB cable to the instrument and the computer. The HFM1 will automatically be detected by the computer, as with any USB device. Open ICT Instrument Software and Search for Devices. Double-click the instrument in the list to connect to it, or select it and click ‘Connect’.

  • Page 17: Connect Via Mcc Mini

    Connect via MCC Mini Ensure that the HFM1 is on. Connect the MCC Mini to your computer, open ICT Combined Instrument software. Tick ‘Auto RF Discover’ and then Search for Devices. The MCC Mini should appear on the list, it will then automatically search for nearby ICT Instruments.

    Sensor Configuration 8.1 Channel Configuration Channel configuration allows you to select a conversion table or script to apply to an input channel. Typically, the appropriate scripts for the sensors will be pre-loaded and configured. 8.2 Measurement Suspend and Time Delay This option allows you to set a time for the instrument to begin logging.

  • Page 19: Conversion Configuration

    8.4 Advanced Configuration The Advanced Configuration section is used to combine 2 single-ended inputs into a single differential input. This should not be altered unless instructed to do so by ICT International technical support. 8.5 SD Card Logging Options Options for additional parameters to be logged to the data file. By default, all these options are enabled.

  • Page 20: Download Data

    Download Data The Data tab can be used for basic data visualisation, SD card management, and to download data files from the instrument. Data is stored on the MicroSD card in csv format. The MicroSD card can also be removed from the logger and read by a computer.
  • Page 21 Manage SD displays the content of the instrument SD card. Refresh List loads the list of files currently present on the SD card. Download File downloads the selected file to the location of your choice. Rename File allows you to change the name of the selected file. Note that if the instrument data file is renamed a new file will be created for measurements from that point onward.

  • Page 22: Installation Of The Hfm1

    Installation of the HFM1 10.1 Location of the measurement area The HFM1 should be installed such to ensure a result which is representative of the element being measured, ideally where one-dimensional heat flow perpendicular to the exterior surfaces occurs. Infrared thermography can be used to assist determine the characteristics of the building component when the internal configuration of the component is unknown.

  • Page 26: Introduction And General Theory

    Introduction and General Theory HFP01 is the world’s most popular sensor for heat flux measurement in the soil, through walls and building envelopes. By using a ceramic-plastic composite body the total thermal resistance is kept small. HFP01 serves to measure the heat that flows through the object in which it is incorporated or on which it is mounted.
