Let me first start by saying I in fact destroyed one of these attempting to install it, the instructions are rotten to say the least but the device is pretty nice and it's not easy to find a device to measure 200v / 200a especially at this price. I'm using the device to measure power coming from my 5 100w solar panels that I have configured in series in order to keep the amps low and make use of smaller / cheaper wiring in doing so. This however drives up the voltage, (currently at 70 to 95 volts) and therefore need a device such as this to measure it.

So, I'd like to leave some instructions on how install this meter and hopefully simplify the process for others.

1. The Red and Black wires go to the positive and negative power supply that will be used to power this meter, It cannot be the same power that you are going to measure. You might find that an old dc adapter from a calculator or something like that will serve the purpose of supplying power to the meter very well, Just make sure it is between 6 and 24vdc

2. Connect the shunt to the Negative Lead in between the power source (Batteries / Solar Panels / Whatever) and the load (Light bulb / Motor / Grid Tie Inverter / Whatever). The bolts on both ends of the the Shunt are intended to be used for these connections.

3. Connect the Yellow wire to the screw on the Source side of the shunt

4. Connect the White wire to the screw on the Load side of the shunt

5. Connect the Green wire to the positive wire coming from the load.

I love this little meter and hope the instructions above are useful, feel free to contact me at roger@3053881080.com for any comments or questions.

I bought this meter because I refused to pay $100 or more for a good digital volt/amp meter. I installed this meter in a battery charger I built. It is great to have one meter read both amps and volts. I admit at first I was skeptical because of the price. I'm glad I took a chance. The meter is very accurate. It was within a hundredth of a volt compared to my Fluke 87 meter. The amp side is accurate too. This meter includes a 200 amp shunt that looks a little cheesy but works well. The power consumption is very low and a touch of the button gives you amp readout. On the back of the meter are pots to calibrate the amp and volt side of the meter. Mine was dead accurate out of the box. The panel is well lit and easy to read across the room.

I plan to order several more to use for the house battery setup in my motor home as well as various other projects. I recommend it highly! This is a crazy low price for a meter with all the functions it has as well as the included shunt.

I bought this item and give it an initial 3 stars because it appears to be a very nice product. However I was greatly disappointed that there was no kind of instructions on how to connect the thing. For Christ sake it has five (50 wires). That in my view was very poor of the venders. No one wants to be stuck with a product they cant use which is were i am kind of at right now with this. Please can simple wiring instructions based on the colors of the pig tail be placed in the product discribsion.i.e which two color wires are the ones to connect to the shunt, and which is for voltage measurement.

Edit* draws to much power, to run off of 9v battery, lasts about 48 hrs.*

1. Changing power supply effects the readings. I could only get it calibrated when using a 9v battery to power the meter. Could not use the 12v battery bank that it was monitoring. Lets hope it runs a good long time on a 9v battery. (edit* only lasts about 2 days, its a piece of crap)
The meter varies 1 volt just by changing the power source from 12v bank to 9v battery. If your readings aren't accurate and you are using the battery that you are monitoring to power the meter. Switch to a 9v before you start messing with the calibration. It took me forever to get it properly calibrated after I messed it all up trying to calibrate it without the 9v. Probably didn't need any calibration at all if I had just used the 9v right off the bat.

2. There are 2 pots on the back of the meter 1 for calibrating volts the other for calibrating amps. However the volt pot affects the amp reading and vice versa. You might have to jump back and forth to get it right.

3. The shunt must go on the negative side of the battery.

In the end I got the meter working. It only took about 8hrs of cursing....and I was one of the lucky ones who got instructions with the meter.

The meter works well, samples fast and is fairly accurate. Here is how you install and setup the meter.

First you MUST use a separate power supply, power supply must fall within range listed, and cannot be connected to what you want to measure!!!

Connect the Red and Black to your SEPARATE power supply.

Connect the White wire to the source side of the shunt. If you are using a battery, this wire goes on the terminal closest to the battery terminal.

Connect the Yellow wire to the load side of the shunt. If you get the White and Yellow mixed up the current measurement will show a negative (-) sign.

Connect the Green wire to the positive (+) terminal of your device, battery, etc.

Now to calibrate the meter, you will have to have a load that you have measured or know the current it draws. The volt/amp meter has two potentiometers (pots). These pots have many turns in them so don't be alarmed if you turn it a few times. Now what I found is that you can chase your tail trying to calibrate the meter if you don't know what you're doing.

Wire up the meter and turn it on with no current draw, verify the voltage is close with a good known Digital Multimeter (DMM) and the current is zero. If it's off don't worry we will calibrate it below.

Looking at the back of the meter with it orientated correctly, up is up. The top pot is for current calibration, the bottom pot is for voltage. Switch the meter to the current setting, connect your known load and adjust the pot until the current is close. Now switch over to the voltage setting and turn the pot until your voltage is close to what your DMM is reading.
