Abstract

The electronic microprocessor controller of a sterilizer includes a circuit board functionally controlled by software. The software includes a fist user operation mode for normal operation of the sterilizer. A diagnostic operation mode is initiated by insertion of a jumper in the circuit board, and provides for repetitive cycle operation without opening the door, quickly advancing to a cycle phase, without completion of intervening phases, printing of variables not available in the user operation mode, and calibration of the circuitry.
