2 Connect a Kelvin cable to the red rear panel jacks. The current
is disabled in this mode so you can leave the cable connected for both resistance and
3 Connect the alligator clip of the Kelvin cable to a grounded point
on the case of the unit under test (UUT). If you leave the clip in place after making the
ground resistance measurement, you can be sure you have the clip on a grounded point
of the case. Make the following case-leakage measurements for the various line
