8． Remarks on measurements
Measuring values may disperse according to measuring circumstances.
Electric Resistor Type Moisture meters use the applications of sensitively electric characteristics of measuring
objects against the moisture contents and the corresponding relations never be a perfectly correlative one- to- one.
In case of measuring wood barks, grains, faces, knots ,albeit the same material , or woods with changes in quality,
salty, contamination, and furthermore with special processing, chemical treatments, it may be necessary to avert
measuring such unfavorable objects, and compensate or average measured values. As for compensating, it is, in
general, based on moisture measurement methods in accordance with a drying process.
(refer to previous page for compensate the kind of wood)
