Volt rotation meter,digital volt meter,car speedometer,digital speedometer,car rotation meter,digital rotation meter,pulse number can be set up.This is a intelligent LCD meter which can monitor battery’s voltage,engine’s rotation

Usage:

1.ignition system with distributor:it is mainly used on old model car,take *-cylinder as example:2 pulses generated by one time engine turning around.

2.ignition system in groups:it is the nowadays applicable scheme, take *-cylinder as example:1 pulse generated by single high voltage transformer when engine turns one time around .

3. sequence of ignition: it would be the future trend as the way used in few car models now.that is: 1 pulse generated by single high voltage transformer when engine turns two times around .thus we set the pulse number as 0.5.
