Hi, I've just projected a board which has the aim of measuring the weight by reading a 6-wire load cell. This board is power supplyed by a trasforme, thus, in this moment, it is isolated from the public power net.
My questions are:
1) Where have I to connect the shield of the load cell cables? To signal ground or to earth? 2) Have I to connect the signal ground to earth? Directly? By a capacitor? 3) Waht happen If I connect the cable shield to signal groud and I don't connect the signal ground to earh?Thank you
