Tried it on DIS on my car and snow blower to see RPM, oscilloscope waveform, Burn duration and spark check voltage on each cylinder. The custom menu options are very easy to use. I wanted to know if the speed of my 1-cylinder snow blower matches my speed per hour. The reading was there, but I had to adjust it from 4 cycles to 2 cycles. And I found the RPMs to be in the 10-20 RPM range. My Fluke 98 and Genisys oscilloscopes have more menus per ms, but this tool is a good tool for the money.
