Hello everybody. This is a circuit where a clockwise rotating field (LED 1 lights up) or the left rotating field (LED 2 lights up) of a three-phase motor / connection can be displayed. I am new to electronics and I found that simple circuit that I do not understand, so I would like to simulate this circuit to understand the function of the capacitors and diodes. I've already looked for tutorials on google and youtube, but I can't find an explicit solution to my problem. Then I started to read the _The EasyEDA Simulation eBook_ article\, so I had my first positive experiences and results with the \*\*waveform tab\. \*\* My current problem is that I don´t know exactly how and where I correctly define the measuring probe and ground for showing me at wich time, how much Volt and Ampere is present at the LEDs. Here you can find a link to the original circuit that I wanted to recreate: [https://upload.wikimedia.org/wikipedia/commons/archive/5/57/20160922134435!Schaltung_Drehfeldmessgeraet.svg](https://upload.wikimedia.org/wikipedia/commons/archive/5/57/20160922134435%21Schaltung_Drehfeldmessgeraet.svg) Thanks for your help.
