PURPOSE:To improve measuring accuracy of moisture content, by not outputting measured value being unsuccessful in grasping by comparing the data voltage of moisture meter with the lowest voltage and confirming whether the grains are grasped under pressure or not by the electrode. CONSTITUTION:The moisture meter A is connected to the computer C and the data voltage Er outputted by the meter A, is compared with the lowest voltage Eo which is lower than the data voltage of excess drying time by the discriminating part C1 of the computer C. Thereupon, when the grains are clogged on the upper part of the meter A and are not flowed to the inside of the through-shaped board 21, the voltage Er becomes abnormally low even if an electric current is turned on and becomes lower than the voltage Eo. In such case, the voltage Er is not outputted by the part C1 and the timer set signal t1 is outputted to the control part C2 and then, the measurement commanding signal (a) is outputted by the part C2 after a prescribed time. Thus, measuring accuracy of the moisture meter can be improved because the measured value is not outputted when the moisture meter is unsuccessful in pressing grains. |
