Am I the only one who got weird resistance readings using a Fluke 87V on a shielded wire run?

I was checking continuity on a 50-foot run in a Cessna 172 last week and got a fluctuating 2-5 ohms, but a simpler meter showed a solid 0.3. Has anyone else had a fancy meter act up on long shielded cables?

Maybe your fancy meter just doesn't like long wires.

River_wright might be onto something with long wires causing issues. The extra resistance can really throw off sensitive readings, especially on cheaper meters. You see it a lot when people try to measure things far from the source. Makes you wonder how much data is actually wrong because of basic setup problems.
