* This device is designed to test and to simulate 1v zirconia and 1v/5v
   titania type oxygen sensors. The simulation can help user to exam
   the function of the ecu. Moreover, it can analyze the type of connection wire.
* Testing 1 ~ 4 wires (with/without heater)

   oxygen sensor (1v zirconia, 1v/5v titania).
* Connection wires analysis (ground, open, heater, ecu power).
* Check the ecu response to the sensor by simulating rich/lean signals.
* Led indication of oxygen sensor signal switching and low power indication.
* With wire piercing clip (easy for connection), 5 minutes auto power
   off, proper sealed control panel, high strength housing.
