Re: TDR with AA-230 Zoom

I just have enough coax to put a connector on ~5ft. I don't know what the "correction"
factor is, I did put the velocity factor in as 82%

It all depends first on whether the correction factor is correct.

I am confused over the 19 ft before the start.? Are you running a 15 foot length into the spool?

I have used the AA-600 and it reports actual length in the graph.

I have an unknown length of Davis Bury-Flex on a Spool and need about 100ft.
I have the settings for the Vol factor (82%) and ran the TDR.
It starts at 14.9ft at the center its 127ft and at the end 238ft.?
Does this mean I have 127ft? I take the center(end of coax) then reflex back?
