A meter in milliseconds can be measured but nesecitas, the multipunto works at 3.4 ms and the monkey point between 1.3 ms. The Landa probe is a current generator if you can measure it with a tester in milli volts that work from 200ml to 800ml, Occilando,

and the step step by step you have to measure with a logic tip to know if the CPU generates the pulses for the step step by step has two entoces coils has 4 positive cables 2 and 2 negatives any other doubt ask me xD
