---- Typical RPM display during operation of the engine
Programmable firing patterns
---- Determined the amount
of pluses(sparks) per engine revolution.
a) When the tach hour meter detect the engine spark plug signal for
more than 1s continuously, the LCD will display the current RPM of
the engine.
b) The RPM will be refreshed every 0.5s.
c) The RPM can be programmed for different pulses per revolution;
Different programming setting will get different RPM; Please follow
the instructions in section 2 below to programming setting for
accurate programming.
This product provides 9 programmable firing patterns, which can be
selected according to the corresponding relationship in the table below.
Note: Some 4 stroke 1 cylinder engine is 1P1R, the setting is the same
way as the 2 stroke 1 cylinder engine.
