NOTES:
The calibration data in this table are based on standard tests by oven-drying of
commercial samples of the various wood species, between 7% and fibre saturation.
Above fibre saturation point (25%-30%) reading are approximate only and generally
apply to wood that has dried and been re-wetted.
The instrument is calibrated for wood at 20°C (68°F). If the temperature of
wood varies by more than 5°C, the meter reading can be corrected approximately by
adding 1/2% for every 5°C below 20°C or subtracting 1/2% for every 5°C above
20°C.
Readings higher by 1%-2% may be obtained where wood has been
impregnated with a water-borne preservative.
High readings obtain with some ply-woods of peculiar composition must be
treated with caution.
