ABSTRACT:
A chemical analysis system for analyzing a plurality of independent specimens that have time varying characteristics includes a circumferential array of analysis regions that hold the specimens. The analytical regions are sequentially and repetitively sensed and resulting analysis signals corresponding to monitored specimen characteristics are stored in corresponding memory locations. A signal transmission channel connected between the sensor and the memory includes a signal storage capacitor and variable slew rate circuitry. The stored data signal value from the location in memory corresponding to the next analysis region to be sensed is applied to the signal transmission channel while the slew rate circuitry is set in a fast slew rate condition to preset the storage capacitor, and then the data signal generated by said sensor is applied to the signal transmission channel while the slew rate circuitry is set in a slow slew rate condition to adjust the data signal value in the storage capacitor to the current analysis signal value provided by the sensor.
