<p>PURPOSE:To easily operate the control device and to improve checking accuracy by providing the device with a decision width updating means for integrating the number of check pulses and the number of dose meters, and when the number reaches the prescribed number of dose meters, computing and updating decision width, storing the updated result, and outputting the stored contents to a dose meter reading part. CONSTITUTION:A data storage circuit 23 receives check pulses (n) from a reading circuit 16 in each input area, and when a comparison decided result is normal, the check pulses (n) are stored by a signal from a comparator 19 and the set number (N) of a dose meters 30 is previously inputted. An arithmetic circuit 24 periodically reads out the contents of the circuit 23, collates the number (W) of check pulses (n) with the set number (N) of the dose meters, and when the number (W) coincides with the number (N), i.e. W=N, executes operation, sends new upper limit value (U) and lower limit value (L) to an upper/ lower limit storage circuit 22 to update the contents, and clears the check pulse data (n) of the circuit 23. The circuit 22 stores and updates the upper limit value (U) and lower limit value (L) generated from the circuit 24.</p> |
