The meters use an inductive pickup attached to the spark plug wire, so no electrical tapping or batteries are required. Encapsulated in an ABS and epoxy housing, each unit resists splash and shock and records hours to 9999.9 with RPM readings up to 99,999.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these hour meters record engine time and RPM?\u003c\/h3\u003e\n\u003cp\u003eThe meters sense ignition pulses through the supplied pickup wire wrapped around the spark plug lead, converting that signal into elapsed runtime and pulse count. When the engine runs the display tallies cumulative hours and shows RPM; when the engine stops, the unit recognizes the loss of pulses and pauses counting.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInductive pickup wire included for non-invasive installation\u003c\/li\u003e\n  \u003cli\u003eCounts up to 9999.9 hours and 99,999 RPM\u003c\/li\u003e\n  \u003cli\u003eAutomatic stop\/start detection — no manual reset during normal use\u003c\/li\u003e\n  \u003cli\u003eLCD display flashes during active counting for clear status\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these meters survive outdoor and heavy-use conditions?\u003c\/h3\u003e\n\u003cp\u003eEach meter is manufactured from sturdy ABS with an epoxy encapsulated case to provide splash resistance and better shock tolerance than exposed circuit meters.
