Mine didn't read Amps only volts.
Frank Kempf
I have this connected to a 12V battery bank to tell me battery voltage and current drawn.

I have not installed it yet as the instructions are poorly written.

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.

I have not installed it yet as the instructions are poorly written. It says if you don't want a common ground disconnect A B. AB is not identified on the instructions provided. This would be every situation where the voltage is over 15vdc. It does not appear to be an easy disconnect to use 12vdc as a meter power and a 100+vdc source. Is there an updated meter installation instruction?
Also the shunt is not shielded so there is no way to easily mount it, If these identified problems get resolved the product would be 5 star buy.

I'm using this on a solar system for the dc loads and voltage it tends to get a bit goofy at times not wanting to read properly but it does ok overall works best at night when solar is not in charging status for what ever reason it does not like measuring draw and charge at the same time. Unit perfect and not buggy when doing amp charge measure OR amp draw measure not both. Using a power adapter 12 volt that plugs in the wall. This thing makes a GREAT blue night light by the way. Considering buying another one for amp Draw so i know how much im pulling from the batteries at night sence it works best at one or the other.
