The compact design and the presence of inner batteries allow to use these tools to measure engine parameters on different vehicles. Anyway, if preferred, connecting the charger supplied in the kit directly to a vehicle, it is possible to use the meter only on it.

In Inner Combustion Engines ICE the correct air-fuel ratio is most important in order that all fuel is used efficiently. The quantity of oxygen into the cylinder determinates how much fuel will be burnt, while the un-burned fuel will be pushed out through the exhaust valve. With the supplied oxygen sensor (Lambda sensor) fitted in the exhaust path, this meter will immediately displays the air-fuel ratio (ideally 14.7 for gasoline) and displays if the fuel mixture is too rich (R) or too lean (L)
