will prompt"CH1: standard probe for primary use，CH2：Ignition probe for
secondary use" Wait a few seconds to enter the oscilloscope interface，other
details, please refer to the above primary, secondary ignition function.
Note:CH1 is primary ignition, CH2 is secondary ignition pay attention to the
probe connected to the channel
4）Primary ignition (current)
①Same as Primary ignition step 1
②After entering the main menu select "Ignition"，then enter
the sub-menu press the up and down keys to select the
"primary ignition (current)"，before entering the operating
interface, it will prompt "must comply with the current
clamp using"
oscilloscope interface.
③Connect current clamp to the oscilloscope CH1, since the
primary ignition oscilloscope is default setting (probe 1X,
time base 1ms), simply connect the current clamp to ignition
coil, then waveform can be visually displayed. As pic-2.
④Press"CH1"， you can view the value and configuration
(configuration has default)
⑤Displayed waveform can be realized through the self-regulating
group, vertical volts / division and trigger their needs
(time base, vertical volts / division and other specific operations,
please refer to the general oscilloscope operation)
Note: If the measured waveform inversed, change the direction of current clamp as
pic-3, the specific use of current clamp, please refer to the purchase
Instructions of the current clamp (To purchase current clamp can contact the
manufacturer for recommended)
wait a few seconds to enter the
Pic-3 use of current clamp
