  • Calibration-inability warning method in analyzing apparatus
    Patent number: 5966676
    Abstract: A calibration-inability warning method in an analyzing apparatus determines in advance when the analyzing apparatus approaches a calibration-inability condition prior to entering calibration inability condition. To do so, coefficient ranges are set, and a calibration coefficient is computed. It is then determined whether the calibration coefficient is within a normal calibration range, a calibration-inability range, or a normal calibration range with no allowance. Signals are generated indicating that the calibration-inability condition is approaching when the calibration coefficient becomes a certain value in the vicinity of the calibration-inability range.
