oxygen sensor

We did not do test this sensor but the tutor did do a demonstration on it infront of the class.He used a vice-grip to hold the sensor and wired it up by having the negative of the volmeter on the case and the positive on the output wire.He used a propane torche to het up the sensor he did this for about 20 seconds and we got a reading of 0.8v he removed the tourch and we got a reading of 0.09v after that he heatedd it for two minutes voltage droped.After doing all these test we found that this sensor was a good and reusable because it met all the necesary specifications

This is a picture i got of google that show a good example of what the tutor showed us in class
