PURPOSE: To connect reliably a connecting coupler with the aimed selective valve of a raw material tank and even if there is a connecting error due to the cause such as ignorance or an illusion, correction of the same is carried out exactly, by a method wherein the title device possesses a control machine actuating the raw material tank so that the raw material tank which is to be selected makes a discrimination signal with instructions from the main control device.
CONSTITUTION: When the receipt of a message is completed, only a selective valve receiving instruction of dispatching of a discrimination signal according to data with actuation of a control machine 28 lights an indication lamp provided on the selective valve. An operator connects a connecting coupler 25 and/or 26 with either of selective valves 15-18 whose indication lamps are lit according to the discrimination signal and the selective valve is opened. In the case where the connection is correct, measurement preparation becomes complete and it enters automatically into a process on and after an autoloader operation. When the indication lamp turns ON and OFF and an alarm sound is emitted, the connection is erroneous, the selective valve also does not open and therefore, connecting operation is performed once more by reconfirming the selective valve which is to be reconnected.
