Abstract : The design and operating principle of an electronic r.p.m. meter are described. As a type of measuring instrument it is more suitable for high speed internal combustion engines than mechanical or electromechanical meters which, when used to count high r.p.m. meter described here is inexpensive, rugged, and simple to service and has low power consumption all of which features make it highly suitable for motor vehicles. The meter features four cold cathode counter tubes and can be enlarged to accommodate eight counter tubes. Because of its low cost and small dimensions, the device might find application in other areas.
