Default Anyone know the capacitance per meter of T&E cable?

Does the tester have TDR?


I think it is a capacitve measurement rather than a true TDR tester...

It should be better.
You can calibrate it by trying it on a known length.


That was my next plan, but I thought I would ask first in case the
answer was way out of its adjustment range[1]. It can cope with 23.5
pF/m to 131.5 pF/m

Makes you wonder why they don't put length markings on the cable like they
do for cat5+.


That would make it simpler!

[1] I was about to say, it would also save having to make up a RJ45 to
crock clip adaptor for attaching to the cable, but then I looked in the
pouch and noticed that is actually one of the standard test lead
harnesses that is supplied with it! ;-)
