Getting back to OP wants to know "how to test" and why on the schedule of test results there is a Zs @ db
"How to test" treat it like a Ze test but with the earth conductor terminated to met.
"Why to test" ascertain what the external resistance is with parallel resistances in place
This needs to be tested and result written down even if the CCU don't feed a sub main.
If you do have a sub main you use this as your Ze at that board
That's what my tutor told me anyways![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
