MO U O gt nog 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 1 296 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 Building material measurements Select the A scale to measure building materials Refer to the following conversion table to obtain the building material moisture value 12 MO220 EU EN V1 5 2 13 Building material and chip board measurements Select the A scale to measure building materials and chip board Refer to the following conversion table to obtain the building material and chip board moisture value equivalents Mati Species Group is A ERN EC EE L E M LA MM 11 0 10 1 8 7 0 10 01 10 31 9 3 7 4 7 4 11 5 11 0 9 8 7 10 8 10 9 9 7 7 9 8 1 12 1 11 6 8 5 10 10 5 11 7 11 5 10 4 8 6 88 12
