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 the fibre saturation point (25%-30%) readings are approximate and generally

apply to wood that has been dried and re-wetted.

 The instrument is calibrated for wood at 68°F (20°C). If the temperature of wood

varies by more than 5°C, the meter reading can be corrected approximately by

adding 1/2% for every 9F (5°C) below 68°F (20°C) or subtracting 1/2% for every 9F

(5°C) above 68°F (20°C).

 Readings higher by 1%-2% may be obtained where wood has been impregnated

with a water-borne preservative.

 High readings obtained with some ply-woods of peculiar composition must be

treated with caution.
