PURPOSE:To take a normal measurement automatically and reduce the frequency of measurement during inspection by providing two kinds of decision making mode. CONSTITUTION:A control part C makes an ON/OFF decision on the switch 24 of a decision making mode means F according to a program in ROM32 and enters automatic measuring operation when the switch is off; and the water content of sample grains is measured five times by a water content measuring means A and stored in RAM34 through a resistance-voltage converting circuit 8 and an AD converter 10, and the mean value is displayed on a display device 46. The mean value is compared with a stop water content (SC) inputted from a stop water content measuring means B to the RAM34 and a measurement time interval is set according to the difference. When the measured water content decreases below the SC, the fuel and fan of a dryer are stopped with relays 54 and 56. When the switch 24 is turned on, an inspection measurement mode is entered to send data on a target water content below the SC to the RAM34, and if a measurement is taken again when the SC is read from the means B, it is decided that a device A is faulty. |
