OPERATIONAL INSTRUCTIONS ON/OFF BUTTON: When the meter is off, momentarily pressing then releasing this button will cause the meter to turn ON, and briefly display the firmware version, then enter Measurement Mode. To turn OFF the meter, depress the ON/OFF button momentarily, then release. The meter will also turn itself off automatically when not in use as described in the autoshutdown section.
3:35 SPECIES TABLE INDEX VALUE SPECIES SETTING (COLON BLINKS DURING EDIT MODE) Example: Species Table Index Value= 3, Species setting = 35 Each time the Species Button is pressed, it will increment the Species Table Index value and show the current setting for that index. The index value will increment to 3 and wrap back to 1. To exit Species Select Mode, momentarily press and then release the HOLD button. PROGRAMMING To select a new Species Table Index, press and release the Species Button.
TAKING MEASUREMENTS In order to take correct moisture content measurements, ensure that the meter’s specific gravity (species) setting is the right one for your species of wood as listed in the Species Adjustment Table*. Be sure to press down firmly on the meter with approximately 1500g (3 pounds) of force to ensure good sensor plate contact with the wood surface. This is especially important on rough-sawn lumber. Do not take readings where there is a noticeable defect or knot in the lumber.
SPECIES CORRECTIONS The dry specific gravity (density) values for a species are based on the best, current world data, and are used to determine the species correction factor within the meter. The values provide average density values for the species. A coefficient of variation (COV) of about 10% describes the variability inherent in many common domestic (US) species.
Wood is not a uniform material. Specific gravity of solid-sawn lumber varies within the piece and among pieces. In the OSU study, the average specific gravity for each species differed from the individual sample by plus or minus 1% to plus or minus 8%. For general applications, average specific gravity values can be found in the Wood Handbook (USDA Agriculture Handbook No. 72, 1999).
1. Select a sample of wood that is approximately 12% moisture content, with all edges being true. Carefully measure the dimensions of the sample using a caliper. You will need the length, width, and thickness. 2. Convert these measurements to feet. 3. Carefully measure the weight of the sample. 4. Convert the weight to pounds. 5. Calculate specific gravity. Example: Length = 10 in. 10 in. / 12 in. = 0.833 ft. Width = 7.5 in. 7.5 in. / 12 in. = 0.625 ft. Thickness = 1.5 in. 1.5 in. / 12 in. = 0.125 ft.
