FirstLook™ ADS ES 100 Theory of Operation
The FirstLook™ sensor looks at the pulse waves generated by the normal operation of an internal combustion engine.
The sensor detects these pulse waves through either the exhaust or vacuum side of the engine. All engines produce a predictable pattern of these pulses which can easily be displayed on most commercially available lab scopes when connected to FirstLook™. This pulse wave is sensed and the voltage is output for display by the lab scope. Any change or irregularity in this predictable pattern can be traced back to problems in the engine. The pulse wave can also be affected by unburned fuel in the exhaust and this abnormality is also detected and displayed. The FirstLook™ sensor does not require any external source of power, so you never need to purchase or replace batteries.
