Digital degree Wheel 4 for ignition timing engine and camshaft tuning up

The Digital Degree Wheel 4 reads 100 times per second the absolute position of the crankshaft in order to not miss also a hundredth of a degree of measurement. It is possible thanks to the mechanical and electronic features of the encoder and of the display unit which are completely designed by Prisma Electronics
