Hello,
I have a #14 one pair (red positive, black negative, and shield) cable is about 1000ft long connecting to an instrumentation in the field from a control systems sending 4-20mA (HART signal). I am getting intermittenly communication errors. I believe there is noise interfernce with the signal, but I want check the cable intergrity first.
How do I check the continutiy of the cable with ohm meter which such long cables from one end to the other?
Thank you
