The Veethree Programmable Electronic Tachometer D37171 is used to measure engine speed by displaying the number of revolutions per minute (RPM) of the engine crank shaft. This model takes input from alternator or ignition coil and through proper filter, it converts into square signal which is fed to frequency to voltage converter IC. This IC generates waves which are 90° apart that drives the air core as per the rpm of the engine.
