Corrections The correction parameters are used when the SFM1 Sap Flow Meter is used to process data on board without the aid of Sap Flow Tool software. 11.1 Probe Spacing Probe spacing must be set to the distance between the needles as they were installed in the stem as this parameter is used in the M lgorithm. -

Spacers can be made from electrical cable sheath stripped from the figure- power cable used for charging the SFM1. se a single edged ra or blade to cut all three spacers the same length with square edges on both sides. - Page 38 Greasing the Needles 12.7 Prior to inserting the needles it is advised to use a small amount of silicon vacuum grease to aid both installation and removal of the needles. This will improve the thermal coupling of the needle to the stem and also minimise the cementing action of sap and gums produced by the tree in response to wounding around the invasive holes drilled into the sapwood. This will be of significant benefit when it comes time for uninstallation.
