How do you wire in this 3 wire Volt Amp meter??

Red wire is the battery or power source black is the ground from battery of power source yellow is what measures the voltage drop across the shunt so the other side of the shunt needs to go to the load the yellow wire to be connected after the shunt meaning load side of the shunt the last picture on amazon is some what confusing but as you can see the red power black ground and yellow is after the shunt on the load side

Go to page on Amazon where the details of the device are displayed on your left. There is also a small drawing that shows you the details of the connections. It is not the best, nor is it in English. I am currently using this device and it works. I also hope this helps.

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

There is a diagram of the wiring schematic on the first review on amazon. I'm wiring tomorrow and can update you

You should be able to find everything you need on this website: http://www.lacemusic.com/wiring.php I think the ground wire hooks to the rest of the grounds and the other two go to the switch. The diagram should give you a good idea.

This is a frequently asked question. The voltage was apparent, however the amperes was guess work and I got the 50%-50% choice wrong. I emailed the seller and they replaced it no charge so I used the other wire. The meter has worked flawlessly for several months.

Did you get the external shunt? Go to ebay and search for.... Amp volt meter...... you will find one like yours along with a drawing.

you have to wire it...but that would be unsafe as it draws too many amps for use with an adapter plug

The power source's plugs needs to be cut and you insert the wires. Your best bet is to check youtube for videos on how to wire the whole thing up. There's a few great ones on there that break it down for you.

Maybe this will help I hook it up to a 1993 chevy truck I hook the voltage wire right to a ignition wire 12 volts in accessory and 12 volts with key on the same wire test with a test light to find the right wire. the voltage measures my battery voltage and when running my charging voltage no problems. I bought the three in one meter voltage temperature and time you can isolate each one or have them all read showing individual readings intermediately so yes it's can read its own power but it is powered by your cars battery I hope this helps you. Ps I'm a auto tech for 37 years now. I Had some problems with the temperature sensor probe but they sent me a new one seems to work okay now. Just so you know it comes in 1 gage not 3 that's just showing you what the gage dose.

All I have is a hand held meter with a needle. It displays 2.1 amps on start up. I am using an Active Air variable speed controller with mine. http://www.amazon.com/gp/product/B003URBQ1M/ref=wms_ohs_product?ie=UTF8&psc;=1

I used a 10 amp fuse and it worked very well. My amp meter never pulled more than 5.5 amps in any mode. Hope this info helps.

Should have a small data info sheet in the bottom of the box it comes in. The connector that has two wires(I used a nine volt battery with a switch), red & black are for display power. The other wires are for voltage sense & amperage (milli-volt) from shunt. Yes, a shunt is required. This is a good meter, just not enough information to support it's installation & calibration. Two adjustments (apex) on the P.C. board are for the calibration of the volt meter & amperage read-outs.

It Doesn't work, I wanted to do the same thing. I purchased 3 of these from different sellers, but none would work measuring amps.

You could do it with a simple relay- but you have to check if this one is compatible with AC current, unless you want to use a DC circuit. Here's link diagrams to both http://4.bp.blogspot.com/_fuBrp5aqZDo/TTQ7KZeAXMI/AAAAAAAAAlU/G3XX2o_e77U/s1600/relay_wiring.jpg http://inspectapedia.com/heat/L4064B_Line_Voltage2.gif

I did not try this into Amperes yetBut I am SURE this multi meter will measure even a .001 ac or dc Volt

YesVoltage side, red wire to +5Vdc supply and black to 5V negative side.meter will read 5.0VdcThen On the current side, red wire to +2Vdc, and load + side.and load negative side to yellow wire.Black wire to 2V negative side. now the meter will read 2V load current.

Just change the plug to a110 volt plug make sure it can handle the amps it will pull when hooked to 110

It should have a seperate sheet from the instruction manual to show how to wire it up. If not call the number to them and have them e-mail you that sheet. If no success can email me at tazmandevil14@gmail.com (subject: Insruction sheet) and I will email it to you.

Has anyone measured the actual output DC voltage when this unit is supplying 2.1 amperes of current? If so, what did your volt-meter read?
