Carlos Maldonado no worries. Just remember, this is for a 50Hz mains supply. 60Hz will give you 3600 rpm on a 4cyl 4 stoke. It's easy enough to work out what to expect from your supply. The more cylinders you have, the lower the reading will be. It's not a calibration, but more of a functionality check. Works with speedometers too, but that's a video for another day.
@@John98512 finally some constructive criticism from you. I'm sorry the free content and education I provided didn't meet your rigid standards. I made one about pizza you'll absolutely love ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1DMNEcXgCso.html I will try better next time, I may even give you a shout-out, though please don't take this the wrong way, I did feel flattered that you said I was cute, but I don't think you're my type. Let's keep this on a purely platonic basis. So going forward, if I make the free content as and when I like and within youtube rules, you can keep carping from the sidelines. After all, the algorithm sees any interaction as a good thing and anthing you have to say really helps me out.
