Cable tester

[John Connor]

Okay, so I just bought a fluke 620 on eBay and I think it might be missing something. The adapter to the other end of the LAN cable. But according to an online store and the manual it doesn't come with it or is it called the RJ45-RJ45 Female Coupler? I don't think that's it.

Items included are:

1 620 Softcase
1 RJ45-RJ45 Straight-Through Patch Cable (EIA/TIA
4 Pair Cat5)
1 RJ45-RJ45 Female Coupler
1 User Manual
1 Cable Identifier #1
1 Quick Reference Card
1 Warranty Registration Card

Manual is here. http://www.fict.ro/manuals_fluke/Man_User_r2_620_us.pdf

I just don't see how I can test for length of cable, shorts and open wires without a transmitter for lack of a better word.

Can you post a picture of what you have? if it's just an female to female RJ45 coupler, those can be had pretty easily..

"transmitter" = Cable Identifier (referred to in manual as "Cable ID Unit").

This is what it looks like. No mention of the cable ID unit. I think the cable ID unit is this device, but I thought there was a small device that you plug into the other end or do you just leave the LAN cable plugged into the router?

Do NOT leave the lan cable plugged in to a switch or router. The manual says specifically not to test on live connections.

You plug the patch cable into the main unit, then on the other end of the cable you put the female-to-female RJ45 coupler, and the "cable ID unit"

If you're testing in wall "home runs" with keystone's, you would plug the main unit+patch cable into the keystone, on the other end of the run the "cable ID unit"

here's a picture of all three, the main unit, the rj45 coupler, and the cable ID unit:

Ahh crap! I don't have item number 1.

 

[John Connor]

This is what I bought. It comes with a fiber tester I plan on selling on eBay. Don't need it.

 

[John Connor]

So item #1 is called the cable ID unit?

fluke 620 - cable identifier #1

You have a fluke? Baby are those things sweet, we use some $10K fluke setups at my college and those make me drool. You are probably missing a single piece, I'd talk to the vendor who sold it to you if I were you. Unless they mentioned the missing piece in their listing, that's very bad salesmanship.

 

[John Connor]

They did mention what you see is what you get. I'm bidding on another one with the cable ID tester and just sell the other one.

But you posted earlier...

Was that just a copy/paste list you found on the internet or actual items you received?
If you really didn't receive the Cable ID, why not contact the vendor for a replacement?

 

[John Connor]

The list of items included I cut and paste from the manual. There is no vendor, I bought it on eBay.

 

[spllmatt]

Did you find anywhere to purchase a replacement for the identifier #1? I am in need of one, called Fluke and since they haven't made them in 8 years they could only give me a part number (936646). No luck finding just that part on the internet. Any help would be very appreciated!

 

[John Connor]

No, I was going to call Fluke and ask them the same question. Looks like you did so I won't be calling. The only thing I can do is buy a whole unit with item #1 on eBay. I might just sell the damn thing and get the other tester I seen for 60 bucks.

 

[imagoon]

You can just buy the identifiers. The have like numbers 1 -> 96. Most cable techs actually buy a pack of 12 - 24 because they can wander around and plug the IDs in and then test all 24 in one batch etc.

--edit--

fluke part N6201 and N6202 identifiers 2-4 and 5-8. Still looking for #1. Not that 2-4 wouldn't work just as well.

#1 -> Fluke #946830

 

[John Connor]

Please give us a link as to where you can buy it!

 

[imagoon]

Well I tried. Looks like that is one of those very long discontinued products.

 

[John Connor]

Figures.

I belive the part is only needed for IDENTIFING cables, IE go to office 1, plug identifier in port, then go to patch panel and start pluggin wires in to meter, when it identifies the probe you left, you found that wire.

The rest of the time its looking for shorts, opens, or lengths based on electrical properties of the cables and while some test do require a connection, most do not, the cable has so much resistance or the reflections time etc... In most cases the only way a tester is identified is the resitor inside it or the voltage, and in both cases in order for that to come down the calbe its going to close a circuit and this show up as a short, so not too many testers use this method. Most use TDR theory any more mas far as I know. Test the meter out on a known cable length or 3 and see what happens. I am pretty sure that manual says it has to be an OPEN cable with no termination.

As to how, with a VOM its called a capacitance test. I assume this is just a fancy VOM.
