  3. Do TDRs need pigtails?

    Yes, they need two wire pigtails with BNC on one side and alligator clips on the other. 18" to 24" would do nicely.

    You have to remember when you say TDR that you are referring to the method \ technology used, not a specific model. The Triplett TDR unit uses a BNC connect, but the PSIBER TDR unit that I have doesn't (it uses an enclosed bullet unit).

    Both are TDR units and both serve the same purpose, but are made by different manufactures.
  6. Would you buy 20 TDR pigtails for your one unit? It will last you a lifetime!

    John Malt got my wiring problems solved (with a little help from Jim, I'd bet). Turned out to be four solenoids gone down plus two zone wires that had been nicked during installation and finally went to ground. We had considered buying a TDR for this, but Russ found the nicks! :clapping::drinkup::waving:

    John Malt don't need no stinking help, he can findshit on his own :laugh::laugh:

    i do have a few questions about the measurements that he got, Billy and i were working on some strange TDR and DMM measurements when he had his stroke.

    on the TDR note, is anyone having issues with TDR measurements?

    42 feet equals 10,484 feet. I think I'm getting the hang of it!
