do you need seperate power to supply this meter

YES-The red wire is connected to a battery sourse. The shunt is connected in ground wire between battery and device. Google the part number YB27VA located on back of meter for complete wiring diagram

No it doesn't, but they are very inexpensive. Besides you won't need it once you've set its output.

No. Your power supply should come with the necessary inputs for it to get power.

No. They are separate. Also, make sure you get a 150 amp inline fuse. The power bright works great.

Hi, Yes, you can use the meter power it and monitor it when connected to the same source. You can also have it be powered by another unit to measure something else. The input voltage ranges from 4.5 to 30 volts. Just make sure to not wire the unit backwards as there is no reverse voltage protection. Note that the brown (or black in some models) wire is the main (common) negative wire and the red wire is the positive power wire. The other color yellow (or white in some models) is the positive voltage measuring wire. For example, you would power the volt meter by connecting it to the brown wire to the negative terminal of the voltage supply and the red to the positive terminal of the voltage supply. You then would connect the yellow white to the positive terminal of whatever you are measuring to it and the brown wire to the negative part (you'll need to solder another to it to make a "Y" connection lead). Last remark, the little screw on the back of the unit allows you to calibrate the unit, you might want to compare and make changes to the unit with another volt meter you already know that is accurate as mine was off by 0.2 volts. I hope this helps!

Hi Jon,The unit is USB powered. You dont need a seperate power unit. The USB cable is included.

Thanks...i used a small 5v USB charger and powered it from my switched AC source. I just don't see where anyone mentions you need an independent supply of 4 to 30 V to run the meter. I was planning to use the power supply I was building into a case with the meter to show voltage and current being used by the connected devices.

I just installed one recently. You are correct, this doesn't plug into an inverter. Instead, the meter display connects only to the solar charge controller for which it is built. Some inverters also have separate remote monitors that you can buy. I chose not to purchase a separate monitor/meter for my inverter since I can clearly see the inverter display where mine is mounted.

Nope. It needs to be powered. I could only get one item at a time to work. If I had 2 or more things plugged in, it wouldn't work at all.

Yes. You would need one meter for each of the hot legs from the generator. That's exactly how I hooked mine up. The beauty is, you can make sure the voltage holds steady, while monitoring the amperage in each side.

Unfortunately you already answered this question. Yes, it will require two separate ports to power this device.

No, you do not need a separate power source. The cooling pad can be powered through a USB port on your computer. I choose to use a separate source to keep the USB port open for other devices.

Only if the tester supplies the load. The power supply gets connected to the tester or the system, there is no provision for in-line. But it was under $10.

No it doesn't. I would suggest either a seperate meter or the system I use which is called TED. TED monitors the entire electrical usage for your home.

Just make shure that what ever your load can pull current wise the wire connecting the load too the shunt and shunt too power source or ground is capable of carrying the current one reason why I bought this meter is because if you have a floating ground it won't fry the meter like it will with one that has a fixed power source I fried one before bying this one do to a small amount of current going from my current source to my voltage supply if there is such an event with this one the reading will just be in acurate pretty bullet proof setup

No. It does not need a power supply. It simply collects the VHF from one antenna and the UHF from another and combines them into one cable.

Yes, This is the best meter for RF generated from smart meters. No, you don,t need anything apart from this meter. If you want to measure signal in power frequency range such as EM field from power line, you have to buy another as this meter will not be suitable for low frequency application
