oscilloscope settings

Hello sir, how are you?I have a firinci 1013d oscilloscope۔And the hentak has a low amp clamp.If I have to check the primary ignition current RAM from these two, which voltage should I set?

I'm not familiar with that scope or amp clamp but, the amp clamp should have a scale printed on it.
 

Typically, the output of an amp clamp is 100mv per Amp for a 20 Amp setting, and 10mv per Amp for a 60 Amp setting. An ignition coil typically draws 5 to 8 amps. Set the voltage scale of the scope to accommodate up to 10 amps.

For a 100mv/A tool, 100mv x 10A would be 1,000mv, or 1 volt. For a 10mv/A tool, 10mv x 10A would be 100mv. You can set the scope voltage scale to a higher voltage but, that will make the the waveform appear smaller on the scope screen. Setting the scope to a lower voltage scale will make the waveform appear larger on the scope screen.
