Description

An instrument used to measure both engine revolutions per minute (RPM) and dwell angle in internal combustion engines. Tachometer Function: The tachometer part measures the engine's rotational speed, typically displayed in revolutions per minute (RPM). This helps drivers, especially in manual transmission vehicles, determine optimal gear shifting points for better performance and fuel economy. Dwell Angle Function: The dwell meter part measures the dwell angle, which is the amount of time or degrees the ignition points in a distributor remain closed, allowing the ignition coil to build up a magnetic field. This is crucial for proper ignition system timing and spark intensity. Usage: The switches on the device allow selection for different engine configurations (e.g., 6 cyl. or 8 cyl.) and measurement modes (tach. or dwell).
