摘要： Checking system for the scanner station of the nucleonic rod-weight control system of a continuous rod cigarette making machine, in which a stable voltage reference is switched into the circuit in place of the usual ionization chamber balance unit and a measurement is made of the difference between the reference voltage and the scanner station radiation reading while no cigarette rod is present, to determine whether the scanner station is free of debris etc. The system opens the internal shutter of the radiation source to enable the measurement to be made and closes the entrance to the scanner unit to prevent escape of B-particles. The reading circuit includes a sample-and-hold facility which enables the reading to be stored so that it can be subsequently read out by an operator or supplied to a centralized computer control system.
