- Range: 120 to 19,999 RPM
- Display waveforms in real time
- Detect and display dwell angle (in high voltage spark plug-wire systems), and ramp time (for COP systems)
- Graph burn time, spark plug voltage, dwell/ramp time, and RPM for each spark, allowing for detection of misfires
- Rechargeable Li-Ion battery
- Useful for troubleshooting: non-starts, misfires, intermittent problems, etc.
