摘要
The present invention is a device to measure and display digitally the automotive engine parameters RPM (rotations per minute), dwell, and points resistance. The general approach taken is to establish a signal with a current controlled oscillator whose frequency is proportional to the above engine parameters. This signal is then processed by a digital counter whose count interval characteristics are determined by the number of cylinders in the automobile engine. The contents of the counter are converted to a digital format and displayed as an accurate representation of the parameters to be measured.
