    Ring continuity test results. Help please.

    I'm rather new to testing and interpreting results. Did a test two weeks ago on a new ring installed then with continuity results L-L 0.37, N-N 0.36, E-E 0.60 and L- E 0.25. All good. Tested it today and got results L-L 0.17, N-N 0.17, E-E 0.39, L-E 0.05. Not good. I'm testing it again tomorrow...
