It’s battery-powered with a replaceable cell, automatically sleeps when idle, and wakes when vibration or signal returns. Built for portable engines, the unit balances simple installation with a robust readout and maintenance reminders.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the inductive clip measure engine RPM?\u003c\/h3\u003e\n\u003cp\u003eThe tachometer detects ignition pulses on the spark plug wire without direct electrical contact, converting those pulses into an RPM reading shown on the display. Because it’s inductive, installation is non-invasive and safe for engines. It works across two-stroke and four-stroke ignition systems when clipped correctly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAttach the included clamp to the spark plug wire—no splicing or wiring required.\u003c\/li\u003e\n  \u003cli\u003eInductive sensing picks up ignition pulses and calculates RPM in real time.\u003c\/li\u003e\n  \u003cli\u003eOperates reliably on engines from 100 to 30,000 RPM with stable readout.\u003c\/li\u003e\n  \u003cli\u003eAutomatically sleeps when no pulses are detected and wakes when engine restarts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat readings and memory features does it provide?\u003c\/h3\u003e\n\u003cp\u003eThe display shows current RPM while the engine runs and switches to total operating time when the engine is off.
