Hi, I got a multimeter with a frequency setting, and also have a car timing light with a detachable coil pickup. I want to be able to read rpms from small 2 stroke engines and I was thinking in using the coil pickup with a zenner diode. The multimeter needs from 200 mv rms up to 10v rms to read properly I remember that the timing lamps work this way: the signal from the pickup is transformed to a pulse that is feed to a scr that pulses the light. Could I connect the MM at the input of the SCR?
