message: :re :File:Megger MTDR1 screenshot.jpg
This screen shot appears to be a two channel display, possibly comparing a good cable to a bad cable.  This needs to be explained.  Also, the upper channel shows multiple traces, why and what does it mean?  The launched pulse is truncated.  Is that the actual shape of the pulse or is it a limit of the display or the instrument?

replies: text: There are actually at least 3 traces; the top is doubled; there are two flat lines at the bottom. Top trace appears to be an open reflection; bottom trace a short. I suspect the launch pulse overdrove the digitizer. I'd just delete the image; the image appears to be more about showing a particular user interface than about TDRs in general. Particularly troubling are the absence of a grid (no ampltude or distance/time scale) and indication of scale or units. The distance between the markers is 595.1, but is that feet, meters, or nanoseconds? It also is confusing with the left-hand 595.1. The entire width of the bottom trace looks to be 1184 unknown units. The marker positions are poorly chosen because they don't imply anything meaningful. The 80 ns might be the pulse width, but the 3 unit separation is a mystery. I don't think the picture shows anything useful, so I'd remove it rather than try to save it. No other article uses it.

thread_title:  External links modified (January 2018) 

message: A web search for reflectometric impulse measurement technique find this page, though it isn't mentioned here.  As I understand it (from watching Nova), RIMT is a similar technique applied to steel cables used for prestressed concrete structures, such as bridges.  RIMT can detect corrosion in steel cables in the same way as TDR detects problems in electrical cables. But that is about as much as I know, which is why I am looking it up.

thread_title:  reflectometric impulse measurement technique 

message: I was going to revert the removal of the following, and then add , but decided
to discuss it here, first.  For one, this reminds me of RIMT (see above), which I believe
should be discussed here, or referenced to a page of its own.  I will let it be discussed
here, to see what should go into the article. Gah4 (talk) 00:47, 24 October 2019 (UTC)

thread_title:  liquids 

message: TDR is used to monitor a coaxial or a cable pair to look for liquid penetration that causes an impedance change along the sensor cable length.  Applications include data centers, double contained piping systems, tank farms, nuclear facilities, water treatment plants, semiconductor facilities, museums, office buildings, generator rooms, hospitals and other critical facilities.  The system allows detection of leaks, growing leaks, multiple leaks, breaks and shorts along the sensor cable with location of the event.PermAlert http://www.permalert.com
