Abstract
A processing unit for normalizing the output data of a gas analyzer in view of zero adjustment data and gain adjustment data formulated by the processing unit controlling air input and span reference simulation of a reference gas. A voltage reference generator is manually variable for calibrating the system while passing a known reference gas through the analyzer, in order to provide a scaling factor for use during output data adjustment. A hold switch is manually actuable by the operator for storing in memory the value of a gas analyzation voltage for permitting adjustment to the output data after the gas is removed from the cell of the analyzer.
