what is meant by "an external shunt"? where do i get one and is there a video on youtube where i can see this being put together?

I just ordered my device, so this "answer" is from principles only. To measure DC current one puts a low ohm resistor IN LINE (in series) with the current carrying wire. Then one measures the voltage drop across that resistor and computes the current by Ohm's law (actually the device does this for you). The resistor can get hot, so it must be air cooled (hence external). It appears that the shunt is included (see picture).

Yes a shunt is necessary to allow the meter to work. I believe it is 500 mA.

The external shunt MUST be used at all times and one end of the shunt MUST be connected to the black wires (which are common). The other end of the shunt would then go to the yellow wire.

There was a printed instruction manual in the box. Before you buy it, you can read it here,http://www.sybausa.com/resource/SY-HUB50044/SY-HUB50044_Manual.pdf,but as the years go by, it could get revised or changed. This answer is specifically for the SY-HUB50044 unit I purchased in may of 2014. It comes with two different cabling options.1) to a USB3 motherboard header, or 2) to a rear panel USB3 port. I used method 2. Both cabletypes were supplied in the box. No power cables were supplied, but my power supply had spare 4-pin and SATA connectors available. I did not have to buy anything special toinstall it in my Antec Minuet 350 case. There was a printed instruction manual in the box.

There is a page in the box (or should be). I sent an email to the manufacturer and they emailed me a diagram (not in the box). Hope this helps.

I think you can find the instruction book on line. It gives very good descriptions of what it works with.

Did you find the unit with a threaded waste port? The waste port should be described or at least a photo provided. Just had to RETURN a unit because of that. IF they had included an threaded piece to install instead of that drop tube requiring a second trap - which actually - I measured a trap will not fit into the space. I guess they figured WE would remake all the pipes under OUR sinks to accommodate THEIR disposals OR call a plumber. Remember 'create jobs'!!!

No you don't need a external power source that's the whole point of this one over other ones that require it red wire is in parrelel with load yellow wire is in parrelel with the shunt along with the ground the shunt is in series to the the load and power source the current is sensed through the voltage drop across the shunt and the voltge is simply measured from the red wire to the black wire last picture has a very simple schematic

You mean without the external cord, that plugs it into wall outlet? Well, new ones are sold with that cable. So try searching used ones, if you absolutely don't want to have that cable included. But may I ask why? what the harm in having it? Do you mean that you later want to have it plugged into a different type outlet, like European? If so - then just buy a European type socket cord and have two of them. If you mean the cables that you use to connect your motherboard to this power unit - pretty much the same applies as with the above cable. Try looking for used ones. But again why? Do you already have your own cables and don't want to pay extra? Or you have the ones that you like and don't want to have extra ones that you don't need? Anyways, the point is that usually these are sold with all the cables necessary to use it out of the box. Meaning that you don't need to buy anything extra to make it work. I didn't seem see an option to not include these cables in the package. Thanks. Alex.

The shunt is needed to carry the current u are using... the meter mesures what is going thru the shunt ..some meters have a internal shunt (only 10 amps)or soothis meter is 100 amps. any more ? Drauschmachin@hotmail.com

Need to buy a separate source........ that is a good thing in my opinion. Most power supplies that are included suck.

michael I believe it comes with a 500amp shunt and can display 0 - 500 amps.

It is called a Magnamount. http://ecx.images-amazon.com/images/I/61xYIEjHp7L._SL1050_.jpgClick on the link or copy and paste it in your browser to see the picture. I think I paid around $22.00 for it.

It doesn't come with any tubing or connectors. Look for s more complete kit. Could be cheaper as they are pricey.

I don't know your particular setup but you need to separate voltages, one to power your volt/amp meter and the one your wanting to monitor. The you monitor you need to setup with your shunt, you have to use a shunt for it to work. If you don't set up a shunt amp meter will show nothing. I hope this helps.

Almost every electronic gadget that you buy today has an external power supply. It is a great way to put one of the components that can fail in a place where it is a (relatively) low cost replacement compared to having to replace the entire monitor.
