Waveform display can be adjusted based on their own through the vertical
volts / division and trigger ways to meet your needs

Secondary ignition
①
Same as Primary ignition step 1
②
After entering the main menu select "Ignition"
，
then enter the sub-menu press
the up and down keys to select "secondary ignition"
，
It will prompt "use
professional ignition probe" before entering the operating interface, wait a few
seconds to enter the oscilloscope interface.
③
Independent ignition to be equipped with an ignition extension cord and high
voltage ignition probe must ignition sensing probe, connect ignition probe to
CH1.
④
Since the secondary ignition of oscilloscope has default settings
（
Probe 10X
，
time base 1ms
）
ignition system with sub-cylinder line, probe with capacitor
(small black squares )side is sandwiched with sub-cylinder line, the other side
connected to the ground or battery negative. If the car is an independent
ignition system
，
you need to buy "independent ignition extension cord"
（
one
side connect to ignition coil, one side connect to spark plug, the role is to
replace the sub-cylinder line
）
ignition probe in independent ignition extension
cord, Step as above.
⑤
Same as Primary ignition step 5
⑥
Same as Primary ignition step 6
