Do it at the connection terminals.

Or by calculation

Take your reading form the light which you got your highest r1+R2 reading!
Attach your L N E probe to the corresponding connections at the light! And shazzam

Same process as you would with the ring like you've said, however you'll need test probes and to take the shade/cover off the light (preferably the furthest inline) and test at the actual connections.

(Although, from what i gather nowadays in colleges that 'live' testing other than ze and pfc is a complete no-no lol. Bullocks.)
