８．NOTES FOR MEASUREMENT
The electric resistance type Moisture meter utilizes the characteristics that the electric characteristics of
an object reacts specially sensitively on its moisture contents, but the co-relations is not perfectly related in
one-to-one ratio. When its composition and proportion differ or change in quality, when contamination,
deformation, salty etc exist, when special processing and chemical treatment are performed even with the
same object, it is necessary to avoid measuremenst at these places or to use values after compensating or
averaging. When the measured values are compensated, it is general to compensate based on the moisture
measurement method by a dry method.
