<p>An improved chemical analyzer calibration system in which energy is applied to a detector. The system includes means which provide an analog signal responsive to energy. The analog signal is then processed to manifest the energy by which the process analog signal is affected by element variations from nominal values in the system. The improvement of apparatus for correcting the effect of the variations on the signal includes ration means, responsive to a first signal applied thereto, and further responsive to a ratio determining signal applied thereto, for providing a signal having a value related to the applied first signal times a ratio determined by the ratio determining signal. There is also included means for applying the analog signal tot he ratio means as the first signal. In addition, there is provided control means for calculating and providing the ratio determining signal while an energy related to a known value is applied to said detector means. The ratio determining signal is calculated to be such that the signal provided by the ratio means has a pre-designated value. The control means then is capable of determining the value related to an unknown energy being applied to the detector means by multiplying the value of the ratio means signal by a factor of the known energy value divided by the pre-designated value.</p> |
