Model L533 all AI not show any value of resistance in MAIN inputs in Debug mode. For sure I connected resistance 140ohm to some AI (group with resistance reading). I expect different values on occupied Inputs but all Analog Inputs have same status I only see rotation numbers from -0,0004569 to -0,0008936 every one second, look like it is not grounded. Input configuration is set to resistance two or three wire. Any Idea?
