Micro SD 6 Connect to the Instrument Connect the USB cable to the instrument. The HFD8 will automatically be detected by the computer as with any USB device. Double click the HFD icon on the Desktop to open the software and click the icon “Connect to HFD”, then click “Find Devices” to search for the instrument and select the named instrument from the Available Devices within the Device Selection Window. - Page 10 Alternatively, if you are using an MCC1 wireless Radio Modem Instrument Information: Fields are provided to Name the instrument and attach a Comment. Entries in these fields will be recorded in a header line within the data file and can be beneficial to recalling important aspects of the experiment after data has been collected.
- Page 11 The name should be indicative of the instrument or treatment and identify its location, as it is the “Name” field which is displayed (along with the serial number) when connecting to the instrument. This is especially valuable if connecting wirelessly to the instrument.

Page 12: Installation
7 Installation: 7.1 Drilling: Drill speed should be high. Only use short increments, stopping regularly to clean the flutes of the drill to prevent friction and heating of the drill bit which will cause the drill to become fluid and take the path of least resistance between fibres rather than through. NOTE: If using a Dremel drill you will need to use the optional drill chuck accessory. - Page 13 Again, a small amount of vacuum grease can be applied (using the offset 10 ml syringe) to aid insertion. Using the Insertion Tool provided, slowly ease the sleeve into position. Never force the sleeve and resist the temptation to “tap” the Insertion Tool to insert the sleeve. Any force greater than finger pressure will buckle the very thin walled sleeve, destroying the sleeve and rendering it unable to be reused, and potentially (if the sleeve can be extracted) ruining the installation site, requiring a completely new site to be started due to...
- Page 14 This ensures the measurement point is located mid way between the sphere of influence of the thermsitors (or measurement points), which are spaced exactly 10mm apart radially along the needle. For thin bark installations, measure bark thickness and calculate the spacer length of 20mm (to the outer measurement point) then subtract 5mm depth below cambium plus the bark thickness to determine the length of spacer required to fit over each needle, including the heater.
- Page 15 7.4 Insulation: Once installed, fasten the base of all needles together to prevent needles from moving relative to each other over time. Then insulate the block on all needles bases by tightly wrapping them with high density foam. Secure the foam tightly at the top of the stem. A bead of Blu-tac or plasticine can be used as a boundary layer.
- Page 16 8 Configuration Enable The Heater by clicking the check box Set Heater power to value of 0.04 W/cm by using the slider bar to achieve the desired value. Select Continuous Heating mode Select prefered logging interval. For long term measurements every 1 minute to 5 mins is adequate.
- Page 17 8.1 Live Data: After installation connect to the HFD Sap Flow Meter and view the HFD Channels Tab. Verification Test It is best to use a low heater power for initial measurements. If night time dT Asymmetrical value for the outer meaurement point (number 1) is persistently below 1 C then heater power should be applied in incremental steps of 0.005 W/cm and checked to determine the optimum heating setting.

MicroSD card. 9.1 MicroSD Card Storage Capacity The storage capacity of the MicroSD card is 4GB. The HFD8 is configured to record the temperatures of all needles; Upper, Lower and Side needles, as well as automatically calculated Symmetrical and Asymmetrical values. -
Page 19: Data File Format
The HFD8 stores data in *.CSV format on the internal MicroSD card. The file structure of the HFD8, whether it uses a comma (,) or a point (.) for the separator, and a point (.) or a comma (,) for the decimal delimiter, is based upon the regional settings of the user’s computer. - Page 20 *.CSV file. 9.2.4 Download MicroSD Card via USB Adaptor The HFD8 data can be downloaded by removing the MicroSD card and putting it in a USB Adaptor (supplied by ICT or available from electronics and computer stores) and inserting the adaptor into a USB port of a computer.
