• 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. • Advanced connection detection: The ST05 automatically detects common wire misconnections like ground, heater wires, disconnected test leads, reversed polarity etc. and displays these on the alphanumeric display. • It only requires the connection of two probe clips to the oxygen sensor wires, and the selection of the oxygen sensor type.
