Multimeters with RPM measurement

RPM

— a function found mainly in “automotive” multimeters intended for use in workshops, service stations, etc. Accordingly, we are usually talking about measuring the speed of an internal combustion engine: by connecting such a device in a special way to the on-board network, you can monitor the parameters of the engine in real time. Note that this function is relevant mainly for the repair and maintenance of relatively old engines that are not equipped with electronic ignition systems and other advanced electronics.
