oxy-wise the intelegent oxygen sensor tester the oxy-wise lambda o2 sensor tester #m99 provides a quick and accurate diagnosis of the vehicles oxygen sensor and allows simulation of the sensor to test the conditions of the wiring harness and the operation of the ecu designed to make diagnosis simple oxy-wise incorporates intelligent sensor wire recognition making it a snap to identify the o2 signal wire heater wire bias voltage and ground oxy-wise automatically identifies the difference between zirconia and titania oxygen sensors and automatically switches operation for proper testing powered by an internal battery oxy-wise is independent of the cars 12 volt power supply making it possible to easily test all oxygen sensors out of the car and on the bench for the first time an indicator is also incorporated to let you know if the battery is low to insuring accurate testing the oxy-wise lambda o2 sensor tester #m99 represents a powerful and intelligent approach to testing lambda control circuits at a very affordable price specifications power supply one 9v battery connectors display controls one bed-o-nails signal clip one ground clip output crossover of lambda sensor displayed as a light path two controls for on/off two controls to simulate rich and lean conditions indent panel five indicators to show 1 heater supply 2 ecu supply voltage 3 open circuit 4 ground 5 internal battery low indicator dimensions 150mm x 75mm x 37.5mm 6 x 3 x 1.5 26
