    ９．NOTES FOR THE MEASUREMENT The electric resistance type Moisture meter utilizes the characteristics that the electric characteristics of an object to be measured reacts specially sensitively on its moisture contents, but the relation is not perfectly related in one-to-one ratio. When its composition and proportion are different or change in quality and contamination exist or special processing and chemical treatment are performed even though the same object, it is necessary to avoid the measurement at these places or to use the measured values after compensating.
