At constant engine speed it reads 1400 and after 1 second it reads 1000 and then back to 1400 with no change in engine speed and 1400 is a ridiculously low reading. The instructions are a joke. He says if less, then make more curves, and if more, then less. Bought so he can tell me RPM, not me. As I said in the title, ridiculously inaccurate and unreliable readings. Can only be used as an hour meter. If you want more, buy something else.
