Oxygen Sensor  Tester and Simulator

Oxygen Sensor Tester and Simulator

The sensor signal output is shown in real time on the bar graph, while a 2 digit alphanumeric display shows the sensor output cross count per second. By pressing the ?Test? button and performing a snap throttle acceleration of the engine, it tests the response time of the sensor and shows a pass or fail result within seconds. Two buttons allows for simulation of rich or lean conditions to monitor response of the engine control module.
