What is the Procedure to Measure Input Resistance to Z2 Coil.

How to Measure Input Resistance to Z2 Shim Circuit and What Should the Resistances be Looking into the Z2 Output Cable FE is troubleshooting problems with the Z2 supply and/or coil and is trying to determine whether the problem is with the Z2 supply, and/or the cabling out to the magnet or the Z2 coil itself. As part of the FE's troubleshooting process, he wishes to measure the input resistance to the external circuit, i.e. the load. But there is nothing documented as to how to do this and what the resistance values should be.
