4.7 Waveform analysis mode
The ignition secondary single-cylinder waveform test is mainly used
to:
a. Analyze the ignition dwell angle of single cylinder.(ignition coil
charging time)
b. Analyze the capability of ignition coil and secondary high
tension circuit (from ignition line to ignition voltage line).
c. Find the improper mixture A/F ratio of single cylinder (from
combustion line).
d. Analyze the capability of capacitance (platinum or ignition
