However, it takes a certain amount of time from the time the electrode rolls begin to rotate until they fully sandwich the sample. Therefore, immediately after the electrode roll starts rotating, the output voltage (moisture voltage) of the roll is set to A.

増大した時点でＡ／Ｄ変換を行なう。(Function) When the electrode roll 2 starts rotating by the moisture meter motor M,
The sample is sandwiched between the rolls, increasing the rotational resistance of the electrode rolls, and the load current of the motor M gradually increases accordingly. Therefore, the change in the load current is measured by the motor load current measuring means a, and when the load current exceeds a predetermined value, the timing determining means immediately commands A/D conversion of the moisture voltage. In this way, immediately after the electrode roll 2 starts rotating, when the load current of the moisture meter motor M is small because a sufficient sample is not yet sandwiched between the rolls, A/D conversion of the moisture voltage is performed. Instead, A/D conversion is performed after a certain period of time has elapsed, when a sufficient amount of the sample has been sandwiched between the rolls and the load current has increased.
