Abstract
The disclosure describes an analyzer controlled by a microprocessor having a memory for diagnosing a vehicle engine. Engine specifications are read into the analyzer by a card bearing: (1) specifications of the engine printed in alpha-numeric form; and (2) a machine-readable code representing a portion of the specifications. A code reader reads the code on the card and converts it into electronic digital signals. The digital signals are converted to a form usable by the microprocessor so that the specifications can be stored in the memory. During analysis, information can be written on the card and stored for use during a subsequent analysis.
